Surface modifications using responsive polymers give access to biomedical applications that rely on switchable properties, such as smart sensors and actuator systems. In this work, thermoresponsive polymer coatings are synthesized silicon oxide surfaces a facile effective two-step grafting-to strategy. Briefly, the substrates first functionalized with poly(dopamine) (poly(DA)) primer layer. Sub...

The moisture uptake of several water-soluble polymers at different humidities was investigated with a thermal gravimetric analyzer equipped with a controlled humidity chamber. The water sorption of poly(acrylic acid) sodium salt, poly(ethylene glycol) and silica, which are known as super absorbers, were examined. In addition, various hydrophilic polymeric materials were selected according to th...

The present research was performed aiming to develop gel with the characteristic of reversible thermosensitive in adsorbing heavy metal ions from its solution. There were three gels used this study adsorb ion salt solution provided Zn(NO 3 ) 2 ; copolymer consisting zwitterionic betaine N,N -dimethyl(acrylamidopropyl)ammonium propane sulfonate (DMAAPS), butane (DMAABS), and DMAAPS copolymerized...

We report on novel type of responsive double hydrophilic block copolymer (DHBC)-based multifunctional chemosensors to Hg(2+) ions, pH, and temperatures and investigate the effects of thermo-induced micellization on the detection sensitivity. Well-defined DHBCs bearing rhodamine B-based Hg(2+)-reactive moieties (RhBHA) in the thermo-responsive block, poly(ethylene oxide)-b-poly(N-isopropylacryla...

A novel linear amphoteric terpolymers based on neutral monomer — N-isopropylacrylamide (NIPAM), ani- onic 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS), and cationic mono- mer (3-acrylamidopropyl) trimethylammonium chloride (APTAC) were synthesized by free-radical polymerization in aqueous solution characterized methods of 1H NMR FTIR spectroscopy, TGA, GPC, Dynamic light scat...

Microwave-, photo- and thermo-responsive polymer microgels that range in size from 500 to 800 microm and are swollen with water were prepared by a novel microarray technique. We used a liquid-liquid dispersion technique in a system of three immiscible liquids to prepare hybrid PNIPAm- co-AM core-shell capsules loaded with AuNPs. The spontaneous encapsulation is a result of the formation of doub...

A facile and one pot synthesis of silver nanoparticles with narrow size distributions using silver nitrate and a copolymer 1 from N-isopropylacrylamide (NIPAM) and mono-(1H-triazolylmethyl)-2-methylacryl-β-cyclodextrin acting as reductant and stabilizer without using any additional reducing agent is reported. The reduction was carried out in aqueous solution under pH neutral conditions at room ...

Synthesis and characterization of block copolymer PEG114-b-P4VP58 and PNIPAM93-b-P4VP58. Materials. Polyethylene glycol methyl ether (CH3O-PEG114-OH, Mn ~ 5000 and the polydispersity index, PDI = 1.05) was purchased from Fluka. The monomer 4-vinyl pyridine (Acros Organics, 95%) was purified by vacuum distillation. N-isopropylacrylamide (NIPAM, Acros Organics, 99%) was purified by recrystallizat...
