Huajaikaew, Eakkapap published the artcileComb-like poly(dodecyl methacrylate) modified SiO2 nanoparticles as nanohybrid coatings: Electron beam grafting and tuning superhydrophobic/water-repellent surface studies, Related Products of esters-buliding-blocks, the main research area is polydodecyl methacrylate silica nanoparticle nanohybrid coating paper superhydrophobicity.

The current research focuses on tailoring silica nanoparticles (SiO2NPs) with comb-like poly(dodecyl methacrylate) (PDMA) brushes and tuning coating parameters based on roller coating process for confining surface morphol. towards hydrophobic and superhydrophobic including water-repellent surface. Electron beam (EB) induced a simultaneous “”graft-from”” polymerization of DMA monomer onto vinyl modified SiO2NPs (SiO2NPs-V) was established in an inventive castor oil/ethanol mixed solvent. Functional surface chem. of SiO2NPs and nanorough surface topog. controlled by NPs content and coating thickness mainly influences the hydrophobic/superhydrophobic, water-repellent, and water absorption properties including gloss values, whiteness and yellowness index of coated papers. The papers coated with SiO2NPs-V-PDMA/PVA of 6-10 wt% with the thickness of ~10-14 μm exhibited matt surface and provided superhydrophobic and water-repellent properties. The coated paper has a desirable and stable water contact angle of 152°, low droplet adhesion with lower dynamic tilting angle (<5°), and 5.3-folds reduced water absorption. Our investigation provides compelling evidence that the SiO2NPs-V-PDMA obtained from EB modification and the developed coating formula for roller-based coating process are realistic approaches for hydrophobic/superhydrophobic coatings and printing inks for paper-based industries.

Yartseva, Vitalia M. published the artcileLyophilic and Sorption Properties of Chitosan Aerogels Modified with Copolymers Based on Glycidyl Methacrylate and Alkyl Methacrylates, Application of Dodecyl 2-methylacrylate, the main research area is chitosan GMA alkyl methacrylate copolymer aerogel sorbent oil sorption; aerogel; chitosan; grafted copolymers; hydrophobicity; oleophilicity; sorption properties.

This paper discusses the influence of the structure of copolymers based on glycidyl methacrylate and alkyl methacrylates with C6-C18 hydrocarbon side groups on the wettability and sorption properties of surface-modified chitosan aerogels. The grafting of copolymers onto the surface of aerogels was confirmed by elemental anal., XPS, and Fourier-transform IR spectroscopy. As a result of the modification, with an increase in the amount of the hydrocarbon substituent alkyl methacrylate, the surface of the resulting materials became hydrophobic with contact angles in the range of 146-157°. At the same time, the water absorption of the aerogels decreased by a factor of 30 compared to that for unmodified aerogels, while the sorption capacity for light oil, diesel fuel, and synthetic motor oil remained at the level of more than 30 g/g. Chitosan aerogels with grafted copolymers based on glycidyl methacrylate and alkyl methacrylates retain biodegradation capacity; however, compared to unmodified chitosan, this process has an induction period.

Dhamo, Lorena published the artcileEfficient Luminescent Solar Concentrators Based on Environmentally Friendly Cd-Free Ternary AIS/ZnS Quantum Dots, Related Products of esters-buliding-blocks, the main research area is silver indium zinc sulfide quantum dot solar concentrator.

Luminescent solar concentrators (LSC) allow to obtain renewable energy from building integrated photovoltaic systems. As promising efficient and long-term stable LSC fluorophores semiconductor nanocrystals like quantum dots (QDs) with size and composition tunable optoelectronic properties have recently emerged. The most popular II/VI or IV/VI semiconductor QDs contain, however, potentially hazardous cadmium or lead ions, which is a bottleneck for com. applications. A simple aqueous based, microwave-assisted synthesis for environmentally friendly and highly emissive AgInS2/ZnS QDs is developed using 3-mercaptopropionic acid (MPA) and glutathione (GSH) and their incorporation into polylaurylmethacrylate (PLMA) polymer slabs integrable in LSC devices (10.4 x 10.4 x 0.2 cm3, G = 12.98). With this simple approach, optical power efficiencies (OPE) of 3.8% and 3.6% and optical quantum efficiencies (OQE) of 24.1% and 27.4% are obtained, which are among the highest values yet reported.

Zeng, Runpeng published the artcileHydrophobic association and ionic coordination dual crossed-linked conductive hydrogels with self-adhesive and self-healing virtues for conformal strain sensors, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is conductive hydrogels adhesive self healing virtue strain sensor.

As a promising functional material, conductive hydrogel has attracted extensive attention, especially in flexible sensor field. Despite the recent developments, current hydrogels still experience several issues, such as limited stretchability, lack of self-recovery and self-healing capability, and insufficient self-adhesion. Herein, dual cross-linked (DC) poly (AA-co-LMA)SDS/Fe3+ hydrogels are fabricated subtly on the basis of ionic coordination interactions and the poly (AA-co-LMA)SDS hydrophobic association networks, which may provide one plausible routine to compensate the mentioned drawback of hydrogels. The hydrophobic association and ionic coordination networks work synergistically to endow the hydrogels remarkable stretchability (1200%), high-fracture strength ( âˆ?20 kPa), and excellent self-healing capability. In addition, the DC hydrogel-based strain sensors displayed a broad sensing range (0 âˆ?900%), conspicuous sensitivity (strain 0% âˆ?200%, gauge factor = 0.53; strain 200% âˆ?500%, gauge factor = 1.23; strain 500% âˆ?900%, gauge factor = 2.09), and pronounced durability. What′s more, the self-adhesive feature ensures the strain sensor always forming a good conformal contact with the skin during human movements and displaying remarkable bidirectional detection capability.

Liang, Zhihao published the artcileSynthesis of UV and thermal dual curing oligomer for solder resist ink using ink-jet printing, Related Products of esters-buliding-blocks, the main research area is UV thermal curable oligomer solder resist jet printing ink.

A solder resist ink for inkjet printing containing the UV and thermal dual curable oligomer was introduced. The oligomer were prepared via copolymerization of an epoxy monoacrylate and three acrylic monomers, and the structures were determined by Fourier transfer IR. Both UV curing process and thermostability were monitored by UV differential scanning calorimetry and thermogravimetric anal. For the photoreaction process, the oligomer using Lauryl methacrylate as the copolymerization monomer possessed the highest reactivity and conversion of carbon-carbon double bond. The oligomers had excellent thermostability, just losing 5.9% at 288°. The solder resist inks containing the oligomers and jetting by the inkjet printer were tested with the adhesion, soldering resistance, and other performances, presenting the outstanding heat resistance and wide application prospects. © 2018 Wiley Periodicals, Inc.

Zhang, Zhuo published the artcileEmulsion-Based Organohydrogels with Switchable Wettability and Underwater Adhesion toward Durable and Ecofriendly Marine Antifouling Coatings, HPLC of Formula: 142-90-5, the main research area is emulsion organohydrogel switchable wettability underwater durable marine antifouling coating.

Marine biofouling has become an extensive problem, resulting in severe harm to marine facilities and maritime operations. Extensive efforts have been carried out to develop effective antifouling strategies for practical applications. Nevertheless, durable and renewable antifouling surfaces with broad-spectrum fouling resistance are in pressing need. Here, antifouling charged organohydrogels (COHGs) possessing amphiphilic and zwitterionic heteronetworks are fabricated by facile emulsion polymerization The synergistic collaboration of covalent linkages, electrostatic interaction, and hydrogen bonding endow the COHGs with excellent mech. properties, including stretchability, compressibility, and recoverability. Owing to the spatial restraints between hydrophilic and oleophilic chains in interpenetrating heteronetworks, the COHGs exhibited significantly low-swellable behavior whether in water or in oil, beneficial to durable applications without impairment of intrinsic performances. The amphiphilic heteronetworks could experience structure rearrangement in response to the surrounding solvents (water or hexadecane), leading to switchable surface wettability. Moreover, the COHGs possess strong wet adhesion to various organic and inorganic surfaces due to synergetic interactions existing at the interface between COHGs and operational substrates, including the hydrophobic effect, electrostatic interaction, and nonswelling behavior, which greatly avoid tedious operation processes during practical application. As for the relationships between the structure and antifouling performances, the elastic surfaces combined with amphiphilic and zwitterionic features reveal remarkable fouling resistance (Navicula sp. and Dunaliella tertiolecta) and recyclable utilization. The COHGs may provide an approach to develop high-performance and ecofriendly antifouling materials.

Fortunato, Giovanni published the artcileHighly Transparent and Colorless Self-Healing Polyacrylate Coatings Based on Diels-Alder Chemistry, Product Details of C16H30O2, the main research area is self healing polyacrylate coating Diels Alder chem transparent colorless.

The efficient integration of reversible polymer networks into acrylate-based polymeric materials is of peculiar interest for the development of coatings that combine high transparency with self-healing ability. In this work, reversible networks are obtained by reacting a series of linear copolymers of furfuryl methacrylate with aliphatic bismaleimides through Diels-Alder (DA) reaction between furan and maleimide moieties. Owing to dynamic crosslinking, the obtained coatings exhibit thermal reversibility, as determined by differential scanning calorimetry and dissolution experiments Furthermore, upon heating over the retro-DA temperature, an excellent recovery of mech. induced surface damages proves successful thermal remendability. Compared to previous reports on DA-based acrylate networks, the presented thermally responsive coatings exhibit outstanding transparency and absence of color, as a result of an accurate choice of suitable monomeric precursors. In addition, a pronounced hydrophobic behavior and excellent adhesive properties make the proposed material particularly suitable for optical applications.

Dinh, Le N. M. published the artcileMiniemulsion polymerization using carboxylated graphene quantum dots as surfactants: effects of monomer and initiator type, Computed Properties of 142-90-5, the main research area is carboxylated graphene quantum dot surfactant vinyl monomer miniemulsion polymerization.

Graphene quantum dots (GQDs) are building blocks of emerging interest for fabrication of polymeric nanocomposite materials with a range of potential applications. In the present work, we have conducted a detailed investigation into the use of carboxylated GQDs as surfactants in aqueous miniemulsion polymerization The cGQDs were prepared by carbonization of dextrose according to a bottom-up hydrothermal approach. It is demonstrated that cGQDs can satisfactorily stabilize miniemulsions of a variety of vinyl monomers including styrene, acrylates and methacrylates. The nature of the initiation system plays a pivotal role in regards to monomer conversion – the water soluble initiator 2,2′-azobis[2-(2-imidazolin-2-yl)propane]dihydrochloride (VA-044) resulted in substantially higher conversions than the oil soluble initiator azobisisobutyronitrile (AIBN). The present results illustrate that these cGQDs have the ability to function as surfactants in miniemulsion polymerization for various vinyl monomer types, which has implications for hybrid nanocomposite nanoparticles and materials synthesis.

Jia, Miaomiao published the artcileThe electro-optical study of Al2O3 nanoparticles doped polymer dispersed liquid crystal films, Formula: C16H30O2, the main research area is electro optical alumina nanoparticle polymer dispersed liquid crystal film.

The electro-optical characteristics of nanoparticles-doped polymer dispersed liquid crystals (PDLCs) have been investigated for display applications. The PDLC samples were obtained by polymerization induced phase separation of the nematic liquid crystal LC-nanoparticles-prepolymer mixtures under UV illumination with a constant intensity. The effect of Al2O3 nanoparticles doping on the PDLC system was studied. It was seen that the electro-optical characteristics of PDLC were dependent on the amount of Al2O3 nanoparticles used. The effect of morphol. on the electro-optical properties was examined, and the exptl. results indicated that the driving voltage was affected considerably by the amount of Al2O3 nanoparticles. The results showed that the nanoparticles concentration can be optimized to obtain promising electronic materials with a min. threshold for display applications.

Guegain, Elise published the artcileRadical Ring-Opening Copolymerization-Induced Self-Assembly (rROPISA), Product Details of C16H30O2, the main research area is radical ring opening copolymerization induced self assembly.

Radical ring-opening copolymerization-induced self-assembly (rROPISA) was performed by copolymerizing benzyl methacrylate and cyclic ketene acetals (CKA), such as 2-methylene-4-phenyl-1,3-dioxolane or 5,6-benzo-2-methylene-1,3-dioxepane, in heptane at 90 °C by reversible addition-fragmentation chain transfer (RAFT) polymerization from a poly(lauryl methacrylate) macro-RAFT agent. The chain lengths of both the solvophilic macro-RAFT agent and the solvophobic block, together with the initial amount of CKA, were independently varied to achieve various compositions The amount of CKA in the copolymers ranged from 4 to �0 mol % by adjusting the monomer stoichiometry, leading to nearly complete degradation for CKA contents above �5 mol %. rROPISA led to stable nanoparticles in all cases, ranging from 40 to 500 nm in diameter, depending on the exptl. conditions, as assessed by dynamic light scattering and transmission electron microscopy. Low average diameters and very narrow particle size distributions were obtained for CKA contents below 20 mol %, except for a targeted solvophobic chain length of 300 that gave narrow particle size distributions up to 50 mol % in CKA. Morphol. investigation revealed the formation of spheres for all copolymer compositions, which was assigned to both the nature of the RAFT agent used and insertion of CKA in the solvophobic block, which prevent the formation of other morphologies.
