Agar microspheres were prepared by water-oil emulsification and cross-linked under alk. condition. The thermoresponsive hydrophobic copolymer, poly(N-isopropylacrylamide-co-lauryl methacrylate-co-acrylamide), was grafted on the agar microspheres via atom transfer radical polymerization The agar microspheres grafted with copolymers were characterized by light microphotog., elemental anal., Fourier transform IR spectroscopy, SEM, and XPS. The chain lengths and hydrophobic monomer ratio of the grafting linear polymer had significant effects on the hydrophobicity and adsorption capacity of agar microspheres at different temperatures The thermoresponsive microspheres were used for separation of proteins and showed binding and release behavior by change of temperatures without change in mobile phase composition Thus, we suggest thermoresponsive agar microspheres as an alternative separation media for all-aqueous biosepns.

Xu, Qingbo published the artcileFabrication of fluorine-free superhydrophobic cotton fabric using fumed silica and diblock copolymer via mist modification, Synthetic Route of 142-90-5, the main research area is superhydrophobic cotton fabric silica diblock copolymer mist modification.

Immobilizing inorganic particles to improve the roughness or coating with fluorinated agents and polysiloxanes to reduce surface energy is the most popular approach for constructing superhydrophobic cotton fabrics. However, the poor durability, health and environmental concerns, and other serious drawbacks limit the application of superhydrophobic cotton fabrics. In the present work, we describe a simple and facile fabrication strategy to construct robust fluorine-free superhydrophobic surfaces of cotton fabric via a mist technique. The modified cotton fabrics were first immobilized by fumed silica (SiO2) particles to improve the roughness and then covered with a diblock copolymer of poly[(Me methacrylate)-b-(lauryl methacrylate)] (PMMA-b-PLMA), which was synthesized by RAFT polymerization, to reduce the fabric’s surface energy. The mist technol. used ensures that the PMMA-b-PLMA covers the SiO2 particles on the surface of the fabric with a thin coating. Therefore, the SiO2 particles were stably immobilized on the fabric surface without reducing the roughness. As a result, the water contact angle (WCA) values of the prepared cotton fabrics reached reached 156.7°±0.5°. Moreover, even after 1600 abrasion cycles or 80 laundering cycles, the WCA values of the fabric samples were still higher than 150.1°±0.5°. The stable superhydrophobic cotton fabric surfaces are useful for self-cleaning, oil-water separation, and other potential areas.

Ghasemzadeh, Hossein published the artcileNanomagnetic Organogel Based on Dodecyl Methacrylate for Absorption and Removal of Organic Solvents, Formula: C16H30O2, the main research area is nanomagnetic organogel acrylic polymer absorption removal organic solvent.

A novel nanomagnetic organogel was synthesized by in situ emulsion polymerization-crosslinking method using dodecyl methacrylate (DDMA) and styrene (St) as monomers, divinylbenzene (DVB) as a crosslinking agent, azobisisobutyronitrile (AIBN) as an initiator, and Fe3O4 as a nanomagnetic particle. Modification of the network was carried out by inclusion of the multi-walled carbon nanotubes (MWCNT) into the organogel matrix. The structure of the nanocomposite was characterized using FTIR spectroscopy, SEM, TEM, TGA/DTG, VSM, and BET anal. The effects of various parameters such as the amount of crosslinker, initiator, Fe3O4, and reaction time as well as monomer ratio on the oil absorption of the organogel were studied. The synthesized organogel can absorb about 35.5, 22.1, 29.86, 14.58, 17.6, 15.3, and 13.7 g·g-1 of CHCl3, toluene, CH2Cl2, hexane, crude oil, gasoline, and diesel oil, under the optimized polymerization conditions, resp. The nanocomposite organogels can be easily separated by a magnetic field after absorption of organic solvents.

Qian, Jiasheng published the artcileOne-Step Nanoextraction and Ultrafast Microanalysis Based on Nanodroplet Formation in an Evaporating Ternary Liquid Microfilm, SDS of cas: 142-90-5, the main research area is ternary liquid microfilm nanodroplet formation nanoextn microanalysis.

Preconcentration is key for detection from an extremely low concentration solution, but requires separation steps from a large volume of samples using extracting solvents. Here, a simple approach is presented for ultrafast and sensitive microanal. from a tiny volume of aqueous solutions In this approach, liquid-liquid nanoextn. in an evaporating thin liquid film on a spinning substrate is coupled with quant. anal. in one step. The approach is exemplified using a liquid mixture comprising a target compound to be analyzed in water, mixed with extractant oil and co-solvent ethanol. With rapid evaporation of ethanol, nanodroplets of oil form spontaneously in the film. The compounds are highly concentrated by liquid evaporation and meanwhile extracted to nanodroplets. A detection limit of nanomolar to picomolar is demonstrated for fluorescent model compounds in only ≈5μL of solution with the entire process taking ≈10 s. The combination of nanoextn. and IR microscopy also enables simultaneous chem. identification. The dynamics of thin film evaporation are revealed using fast imaging. The principle behind this approach is general, providing a powerful technique for fast and sensitive chem. anal. of a vast library of compounds for environment monitoring, national security, early diagnosis, and many other applications.

Bryuzgin, Evgeny published the artcileThe Superhydrophobic State Stability of Coatings Based on Copolymers of Glycidyl Methacrylate and Alkyl Methacrylates on Cotton Fabric Surface, Safety of Dodecyl 2-methylacrylate, the main research area is glycidyl alkyl methacrylate copolymer cotton fabric coating.

We suggest a simple and reproducible strategy for fabricating durable superhydrophobic coatings on the basis of series of functional random copolymers of alkyl methacrylates and glycidyl methacrylate on cotton fabric surface. The procedure consists of the fabric treatment by solutions of copolymers in methylethylketone and following heating at 140°C. The initial contact angles of obtained coatings on fabric surface achieve 165°. The dependence of superhydrophobic properties of coatings based on copolymers of glycidyl methacrylate and alkyl (meth)acrylates (with alkyl radicals C4-C18 in side chains) attached to the cotton fabric surface was studied. The comparative anal. of superhydrophobic state stability of polymer coatings during long-term contacts with aggressive media is presented. We evaluated the contact angles stability as a function of prolonged contact of polymer coatings with water under saturated vapor conditions, organic solvents, and synthetic detergents. Polymeric coatings based on a copolymer of lauryl methacrylate (C12) and glycidyl methacrylate provide better stability of superhydrophobic properties compared with other copolymers of alkyl methacrylates.

Liu, Guiju published the artcileRole of refractive index in highly efficient laminated luminescent solar concentrators, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is laminated luminescent solar concentrator refractive index.

As a large-area solar radiation collector, luminescent solar concentrators (LSCs) can be used as power generation units in semitransparent solar windows, modernized agricultural greenhouses and building facades. However, the external optical efficiency and long-term stability of the LSCs limit their practical applications due to the sensitivity of the emitters to the light and environmental conditions. Here, we used the concept of “”laminated glass”” to prepare LSCs, which consist of two waveguide layers and the quantum dots (QDs)/polymer interlayer, and we tune the refractive index of the different parts of the system to improve the external optical efficiency and stability of the LSCs, simultaneously. The waveguide layer can be glass, quartz, polymethyl methacrylate (PMMA) and other transparent materials. The CdSe/CdS core/shell QDs were used as fluorophores to prepare the interlayer of the LSCs. The external optical efficiency of the laminated LSCs is associated with the refractive index of the three layers: the closer the refractive index, the higher the ηopt. The highest external optical efficiency of 3.4% has been achieved for the laminated PMMA/QDs-polymer/PMMA LSCs, which improved ~92% compared to the single-layered CdSe/CdS based LSCs. To the best of our knowledge, this is the highest efficiency for the LSCs based on CdSe/CdS QDs. These results pave the way to realize high efficiency laminated windows as power generation units by suitably tuning the structure of the LSC, and provide the theor. guidance for the LSCs utilized in building integrated photovoltaics.

Dilek, Aycan published the artcileThe Use of Poly(dodecyl methacrylate-co-N-isopropylacrylamide) Gel for the Separation of Limonene + Linalool Mixture, Related Products of esters-buliding-blocks, the main research area is dodecylmethacrylate isopropylacrylamide gel separation limonene linalool mixture.

Poly(dodecyl methacrylate-co-N-isopropylacrylamide) gels were prepared with and without a pore former (PEG) in ethanol at 70°C by free radical crosslinking polymerization method. These gels were used to sep. limonene + linalool mixtures with different fractions. The selectivity values were higher than 1 for each gel synthesized with PEG and without PEG. In equilibrium, selectivity values of gels synthesized without PEG in 90/10, 80/20, and 70/30 limonene + linalool binary mixtures were calculated as 1.1, 1.9, and 2.1, resp. The corresponding gels synthesized using PEG have selectivity values as 1.3, 1.9, and 2.2. Despite slightly effect of pore former on selectivity, it has a relatively significant effect in time regions before arriving equilibrium, giving the idea of selecting optimum time region to sep. binary mixtures Solubility parameter of the gel was predicted by group contribution methods to determine the relationship between selectivity and solubility parameter difference of binary combinations of limonene, linalool and gel. Solubility parameter difference calculated from Hoy method showed that the value of each solubility parameter contribution for gel-linalool binary was the lowest with the values of 0.02, 1.7, and 4.8 for disperse, polar and H-bonding contributions, resp. verifying the selectivity of the gels for linalool. The gel synthesized using PEG shows a swelling value change for temperatures higher than 40°C in the direction of decreasing but the gel synthesized without PEG has approx. constant equilibrium swelling value (ESV). This result indicates that the use of a pore former may be an important parameter in the recovery process of the extracted components after the separation procedure.

Kovylin, R. S. published the artcileOne-step photolytic synthesis of hydrophobic porous polymer materials by the copolymerization of the dimethacrylate-alkyl methacrylate system in the presence of methanol, Application In Synthesis of 142-90-5, the main research area is methacrylate system hydrophobic porous polymer material methanol photopolymerization.

Hydrophobic porous polymer materials were synthesized by one-step visible light polymerization from compositions consisting of phthalate-containing oligoester di(meth)acrylate MDP-2, methanol, and alkyl methacrylate (Bu methacrylate, ethylhexyl methacrylate, iso-decyl methacrylate, lauryl methacrylate, and stearyl methacrylate) compositions The highest hydrophobization effect is observed for stearyl methacrylate. The maximum MDP-2 block photopolymerization rate is by 16-50 times higher than that of alkyl methacrylates. The sp. surface areas of the synthesized porous polymers reach 4.2 m2 g-1, and the pore size ranges from 5.5 to 17 μm. The addition of stearyl methacrylate to the composition leads to the pore size distribution narrowing. The principal possibility of using these photopolymerizable compositions as stationary phases for liquid chromatog. is shown.

Zhao, Yi published the artcileDesign and characterization of oil-in-water nanoemulsion for enhanced oil recovery stabilized by amphiphilic copolymer, nonionic surfactant, and LAPONITE RD, Related Products of esters-buliding-blocks, the main research area is oil water nanoemulsion amphiphilic copolymer nonionic surfactant LAPONITE.

The application of nanotechnol. in the oil and gas industry has attracted widespread attention in recent years. This study aims to develop a nanoemulsion (NE) for use in enhanced oil recovery (EOR). The NE stabilized by anion amphiphilic copolymer, nonionic surfactant (Brij30) and modified LAPONITE RD was prepared by the phase inversion composition (PIC) method. The appearance of the emulsion is translucent and the average particle size is less than 60 nm. The micromorphol. and interfacial tension (IFT) are examined using transmission electron microscopy (TEM) and a spinning drop IFT meter, resp. The NE possesses good stability evaluated by conductivity and particle size tests. The absolute value of the zeta potential of NE increases when modified LAPONITE RD is added. In a core flooding experiment with an artificial sandstone core, the NE flooding increased oil recovery by 23.53% compared to water flooding.

Shabnam, Rukhsana published the artcileCumulative effect of hydrophobic PLMA and surface epoxide groups in composite polymer particles on adsorption behavior of congo red and direct red-75, Related Products of esters-buliding-blocks, the main research area is composite polymer particle hydrophobic PLMA epoxide dye adsorption.

Industrial applications of hydrophobic materials are numerous, particularly as adsorption beads to remove organic pollutants. In this research combined effect of hydrophobicity and reactive epoxide group on the adsorption behavior of dye mols. by composite polymer particles was investigated. Lauryl methacrylate (LMA) a poor water soluble long chain vinyl monomer is com. available. Polystyrene/poly(LMA-divinyl benzene) or PS/P(LMA-DVB) composite seed particles were first prepared by slightly modified activated swelling of micron-sized PS seed particles utilizing either water or water-ethanol dispersion medium. The influence of poly(vinyl alc.) (PVA) as steric stabilizer on the size and size distribution was evaluated. The poor solubility of LMA in the continuous phase hindered the homogeneous swelling of PS particles even in the presence of ethanol (5% weight/weight) and resulted in fairly polydispersed PS/P(LMA-DVB) composite seed particles. The composite seed particles were then functionalized with epoxide group by seeded polymerization of glycidyl methacrylate (GMA) to produce PS/P(LMA-DVB)/PGMA composite polymer particles. The epoxide functionalized PS/P(LMA-DVB)/PGMA composite polymer particles were used to adsorb two kinds of azo dyes, congo red (CR) and direct red-75 (DR-75). The effects of initial dye concentration at 303 and 323 K on adsorption behavior were investigated and the adsorption was explained by adsorption isotherms. Temperature dependent adsorption measurements were also carried out at identical initial dye concentration The adsorption results showed that inclusion of reactive epoxide group on/near the surface of hydrophobic PS/P(LMA-DVB) composite seed particles improved the adsorption capacity of dye mols.
