Gong, Xuanang published the artcileEthyl cellulose based self-healing adhesives synthesized via RAFT and aromatic schiff-base chemistry, COA of Formula: C16H30O2, the main research area is ethyl cellulose grafting vanillin lauryl methacrylate; Adhesives; Ethyl cellulose; Schiff base; Self-Healing; Vanillin.

In this work, reversible addition-fragmentation chain transfer (RAFT) polymerization and Schiff base chem. was combined to fabricate self-healing adhesives. An esterification reaction was first performed to prepare Et cellulose based macroinitiators. Then, a “”grafting from”” RAFT of vanillin methacrylate and lauryl methacrylate was used to obtain graft copolymers. DSC result showed that the glass transition temperature was manipulated via changing the ratio of vanillin and fatty acids moieties. NMR spectrum anal. demonstrated the presence of aldehyde groups, which were available for the dynamic crosslinking to generate a network as self-healing adhesives. The adhesive test showed that the shear strength could reach 0.81 MPa with a self-healing efficiency of 98.7%. The bottlebrush structures of copolymers and reversibility of Schiff base chem. might collaboratively contribute to the high self-healing efficiency. This study provides a facile way to fabricate high-performance self-healing adhesives from Et cellulose and renewable resources.

Boscan, Freddy published the artcileIncorporation of Very Insoluble Monomers in Waterborne Coatings, Application In Synthesis of 142-90-5, the main research area is waterborne coating insoluble monomer.

The benefits of polymerizing very insoluble monomers in aqueous media, avoiding the use of energy-intensive procedures, by implementing two novel synthesis techniques based on the emulsifier combination in emulsion polymerization and on miniemulsification by phase inversion temperature are investigated. The performance of standalone polymers consisting of monomers, namely lauryl methacrylate, isobornyl acrylate, and 1H,1H,2H,2H-perfluorodecyl acrylate, and of formulated binders with these monomers incorporated either through blending or in situ polymerization, is evaluated with special emphasis on their water-barrier properties (e.g., uptake, whitening, immersion, and vapor resistance) and on their chem. resistance. The performance of the standalone polymers is found to be similar to that of polymers prepared by high-shear miniemulsion polymerization, while the performance of the formulated binders is generally superior to a com. coating formulation based on a binder recommended for water resistance.

Huang, Hsiu-Ying published the artcileEco-Friendly, High-Loading Luminescent Solar Concentrators with Concurrently Enhanced Optical Density and Quantum Yields While Without Sacrificing Edge-Emission Efficiency, Name: Dodecyl 2-methylacrylate, the main research area is luminescent solar concentrator optical density quantum yield.

A luminescent solar concentrator (LSC) consists of loaded luminophores and a waveguide that can concentrate direct and diffuse sunlight, which is a crucial ingredient for developing solar glasses. In general, the loading concentration in LSCs is strongly restricted (typically <1 weight%) to mitigate concentration-induced quenching (CIQ), reabsorption losses, and aggregation-induced scattering (AIS). However, this will induce transmission losses in particular for thin-film LSCs. To address all aforementioned issues, large-Stoke-shift LSCs with different loadings are simply prepared based on thiolated gold nanoclusters (GSH-AuNCs) dispersed in the polyvinylpyrrolidone (PVP) matrix. In contrast to conventional luminophores with a severe CIQ effect, photoluminescence quantum yields (PL-QYs) can be significantly enhanced up to ≈25% (from 0.5 to 1%) even under high loading of ≈26 weight%. Such PL-QY enhancement is attributed to the synergistic effects of the suppression of non-radiative relaxation and enhancement of radiative decay processes due to surface ligand-matrix coordination. In addition, our high-loading LSCs also exhibit excellent optical quality and film uniformity without introducing noticeable AIS effects. Thanks to those unique properties, eco-friendly LSCs with high optical d. can still hold a high edge-emission efficiency of ≈70% due to minimal reabsorption and scattering losses, yielding an external quantum efficiency of ≈15% at the wavelength of 400 nm.

Alberg, Irina published the artcileEffect of Core-Crosslinking on Protein Corona Formation on Polymeric Micelles, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is crosslinked polyhydroxypropylmethacrylamide preparation nanoparticle blood protein zeta potential; asymmetrical flow field-flow fractionation; core-crosslinking; polymer micelles; protein corona.

Most nanomaterials acquire a protein corona upon contact with biol. fluids. The magnitude of this effect is strongly dependent both on surface and structure of the nanoparticle. To define the contribution of the internal nanoparticle structure, protein corona formation of block copolymer micelles with poly(N-2-hydroxypropylmethacrylamide) (pHPMA) as hydrophilic shell, which are crosslinked-or not-in the hydrophobic core is comparatively analyzed. Both types of micelles are incubated with human blood plasma and separated by asym. flow field-flow fractionation (AF4). Their size is determined by dynamic light scattering and proteins within the micellar fraction are characterized by gel electrophoresis and quantified by liquid chromatog.-high-resolution mass spectrometry-based label-free quant. proteomics. The analyses reveal only very low amounts of plasma proteins associated with the micelles. Notably, no significant enrichment of plasma proteins is detectable for core-crosslinked micelles, while noncrosslinked micelles show a significant enrichment of plasma proteins, indicative of protein corona formation. The results indicate that preventing the reorganization of micelles (equilibrium with unimers) by core-crosslinking is crucial to reduce the interaction with plasma proteins.

Kafetzi, Martha published the artcileMultifaceted pH and Temperature Induced Self-Assembly of P(DMAEMA-co-LMA)-b-POEGMA Terpolymers and Their Cationic Analogues in Aqueous Media, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is amphiphilic polymethacrylate diblock terpolymer self assembly RAFT polymerization.

This work focuses on the synthesis of novel amphiphilic block terpolymers of the type poly[(2-(N,N-dimethylamino) Et methacrylate)-co-(lauryl methacrylate)]-b-poly[(oligo ethylene glycol) Me ether methacrylate] (P(DMAEMA-co-LMA)-b-POEGMA) by reversible addition-fragmentation chain transfer polymerization The cationic amphiphilic polyelectrolyte analogs P(QDMAEMA-co-LMA)-b-POEGMA are obtained through quant. quaternization of the DMAEMA segments. Mol. characterization by size exclusion chromatog., NMR, and Fourier Transform IR spectroscopies indicates the successful synthesis of these novel series of block terpolymers. The amine forms of the block copolymers respond to pH and temperature changes in aqueous solutions by forming unimol. or multichain nanoaggregates of varying size, micropolarity, and internal structure, as indicated by light scattering and fluorescence spectroscopy techniques. At neutral and basic pH, the existence of micellar like nanoassemblies is observed in the solutions of P(DMAEMA-co-LMA)-b-POEGMA terpolymers, while aggregation into micellar-like clusters take place at temperature values above room temperature due to the presence of the hydrophobic LMA segments. Unexpectedly, the cationic polyelectrolytes P(QDMAEMA-co-LMA)-b-POEGMA counterparts show temperature responsiveness as a consequence of the amphiphilicity of the polymeric system.

Balafouti, Anastasia published the artcileP( OEGMA-co-LMA ) hyperbranched amphiphilic copolymers as self-assembled nanocarriers, Category: esters-buliding-blocks, the main research area is hyperbranched amphiphilic copolymer preparation curcumin drug delivery bioimaging.

We report on the synthesis of novel amphiphilic hyperbranched copolymers, namely Hyperbranched-[poly (ethylene glycol) Me ether methacrylate-co-lauryl methacrylate] (H-[P(OEGMA-co-LMA)]), obtained by reversible addition-fragmentation chain transfer (RAFT) polymerization utilizing the divinyl monomer, ethylene glycol dimethacrylate (EGDMA) as the branching agent. Mol. characterization by size exclusion chromatog. (SEC) and proton NMR (1H-NMR) spectroscopy indicated the success of the polymerization The self-assembly behavior in aqueous media was investigated by light scattering techniques and fluorescence spectroscopy. The hyperbranched copolymers form multimol. aggregates of nanoscale dimensions with a low critical aggregation concentration In addition, the model hydrophobic drug, curcumin (CUR), known also for its intrinsic fluorescence properties, was used in order to investigate the H-[P(OEGMA-co-LMA)] copolymers drug encapsulation ability. Curcumin is successfully loaded into the polymeric nanoparticles, as confirmed by dynamic light scattering and UV-Vis spectroscopy. Interestingly, curcumin hydrophobic interactions with the hyperbranched copolymers result in more well-defined co-assembled nanostructures, in terms of size and size distribution. The mixed copolymer-CUR nano-assemblies consist of small size nanoparticles (<100 nm) which exhibit relatively high size uniformity, colloidal stability and fluorescent properties. Overall, results signify that the biocompatible H-[P(OEGMA-co-LMA)] nanostructures could potentially serve as nanocarrier systems for drug delivery and bio-imaging applications.

Zhao, Caimei published the artcileFabrication of hydrophobic NiFe2O4@poly(DVB-LMA) sponge via a Pickering emulsion template method for oil/water separation, COA of Formula: C16H30O2, the main research area is nickel iron oxide polydivinylbenzenecolaurylmethacrylate sponge; sponge Pickering emulsion template method oil water separation.

Super-hydrophobic porous absorbents are convenient, low-cost, efficient and environment-friendly materials in the treatment of oil spills. In this work, a simple Pickering emulsion template method was employed to fabricate an interconnected porous poly(DVB-LMA) sponge. A new co-Pickering stabilization system of Span 80 and NiFe2O4 nanoparticles was used to prepare ultra-concentrated internal phase water-in-oil (W/O) emulsions. After further polymerization, the resulting sponges were generated, which exhibited excellent adsorption selectivity due to the super-hydrophobicity and super-lipophilicity. Furthermore, the characterization results indicated that the composites had superior thermal stability, low d., high porosity and a flexible three-dimensional porous structure. Besides, the addition of nickel ferrite nanoparticles provided the materials with extra magnetic operability. High oil adsorption capacity (up to 36.9-84.2 g g-1), high oil retention, fast adsorption rate and superior reusability allowed the materials to be applied in the treatment of oily water.

Zhong, Hanyi published the artcileMinimizing the HTHP filtration loss of oil-based drilling fluid with swellable polymer microspheres, Application of Dodecyl 2-methylacrylate, the main research area is HTHP filtration oil drilling fluid swellable polymer microsphere.

Filtration control of drilling fluid plays an important role in the process of wellbore construction and ensures the success of drilling operation. A swellable polymer microsphere (SPM) of methylmethacrylate (MMA), Bu acrylate (BA), and lauryl methacrylate (LMA) was synthesized with suspension polymerization Its swelling property was characterized by oil adsorption capacity measurement. First, the effect of SPM on the filtration and rheol. properties of virgin organic clay dispersion was investigated. Then the filtration and rheol. properties of mineral oil-based drilling fluid in the presence of SPM were elucidated under the resp. conditions of hot aging temperature, oil to water ratio and d. Furthermore, the filtration control properties between SPM and two traditional filtration loss additives including modified lignite and asphaltic additive was compared. Addition of SPM exhibited obvious influence on the viscosity of oil-based drilling fluid especially at high concentration of 3 w/v%, therefore, a concentration of lower than 1.5 w/v% was recommended. After hot aging at 200°C, the oil-based drilling fluid containing 1 w/v% SPM exhibited an API filtration loss decrease of 85%, and HTHP filtration loss decrease of 79% in comparison with the base fluid. After hot rolling at 180°C, the API filtration loss decreased by 2%, 24% and 53%, and the HTHP filtration loss decreased by 42%, 54% and 65% resp. when 1 w/v% asphaltic additive, modified lignite and SPM are in the presence of the base fluid. Besides decreasing the filtration loss volume under high temperatures, incorporation of SPM also improves the filter cake quality of oil-based drilling fluid. SPM is capable of adsorbing considerable base oil and become swellable. The swellable polymer microspheres with favorably deformable and compressible properties can effectively fill the voids of filter cake and reduce the permeability, which leads to low filtration loss and minimization of solids invasion.

Guo, Fenghao published the artcileFunctional monodisperse microspheres fabricated by solvothermal precipitation co-polymerization, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is polymer microsphere solvothermal precipitation copolymerization.

Simultaneous achievement in high solid content and high microsphere yield is deemed a challenge in the fabrication of monodisperse microspheres by precipitation polymerization We herein demonstrate that micro-sized monodisperse poly(methacrylic monomer-divinylbenzene) microspheres containing epoxy, lauyl, carboxyl and hydroxyl functions can be fabricated by solvothermal precipitation co-polymerization at 20% (mass) monomer loading with over 94% microsphere yield. The morphol. and porosity of the obtained particles can be readily tuned by cosolvent-acetonitrile binary solvents. Addition of a small amount of cosolvent that has similar solubility parameter to that of the functional monomer can significantly improve the monodispersity of the obtained microspheres. When THF was used as the co-solvent, the surface area of the highly porous microspheres achieved higher than 400 m2·g1. Solvothermal precipitation co-polymerization can be expected in scale-up fabrication of various monodisperse functional microspheres free of any surfactant and additive.

Gmur, Tobias A. published the artcileTowards a Polymer-Brush-Based Friction Modifier for Oil, Category: esters-buliding-blocks, the main research area is polymer brush oil friction modifier.

To meet the need for oil-compatible friction modifier additives that can significantly reduce energy consumption in the boundary-lubrication regime, a macromol. design approach has been taken. The aim was to produce a lubricious polymer film on the sliding surfaces. A series of readily functionalizable block copolymers carrying an oleophilic poly(dodecyl methacrylate) block and a functionalizable poly(pentafluorophenyl methacrylate) block of various lengths was synthesized by means of reversible addition-fragmentation chain-transfer (RAFT) polymerization The poly(pentafluorophenyl methacrylate) block was used to attach surface-active nitrocatechol anchoring groups to the polymer. The friction-reduction properties of these polymers were assessed with 0.5 wt% solutions in hexadecane by means of rolling-sliding macroscopic tribol. tests. Block copolymers with roughly equal block lengths and moderate mol. weights were significantly more effective at friction reduction than all other architectures investigated. They also displayed lower friction coefficients than glycerol monooleate-a com. used additive. The film-formation ability of these polymers was examined using a quartz-crystal microbalance with dissipation (QCM-D), by monitoring their adsorption onto an iron oxide-coated QCM crystal. The polymer with highest lubrication efficiency formed a thin film of ∼ 17 nm thickness on the crystal, indicating the formation of a polymer brush. Interferometric rolling-sliding experiments with the same polymer showed a separating film thickness of ∼ 20 nm, which is consistent with the QCM-D value, bearing in mind the compression of the adsorbed layers on the two sliding surfaces during tribol. testing.
