Item pH-sensitive Hybrid Hydrogel Materials with Incorporated Nanoparticles(Sumy State University, 2014) Kryklia, S.O.; Samchenko, Yu.M.; Poltoratska, T.P.; Konovalova, V.V.Synthesis and physico-chemical studies of new promising hybrid hydrogels based on polyvinyl alcohol (PVA) acetales and copolymer hydrogels based on vinyl monomers have been studied. Acrylamide, N-Isopropylacrylamide and Acrylic acid were used as components of interpenetrating networks based on PVA acetals. Sponge acetales of polyvinyl alcohol were used as enforcing net. Study of swelling kinetics as compared to solvents of various nature (water in various pH, ethanol, toluene etc) was carried out. IR comparative spectra were obtained for different composites. High anti-bacterial action of the synthesized nanocomposites containing silver towards gram-positive and gram-negative bacteria has been demonstrated.Item Hybrid Hydrogel Materials with Incorporated Nanoparticles(Sumy State University, 2013) Samchenko, Yu.M.; Kryklia, S.O.; Poltoratska, T.P.; Суходуб, Леонід Федорович; Суходуб, Леонид Федорович; Sukhodub, Leonid Fedorovych; Isheikina, Yu.O.; Makarenko, V.I.; Konovalova, V.V.Synthesis and physico-chemical studies of new promising hybrid hydrogels based on polyvinyl alcohol (PVA) acetales and copolymer hydrogels based on vynil monomers have been studied. Acrylamide and Acrylnitrile were used as some of components that carry various fillers . Sponge acetales of polyvinyl alco-hol were used as enforcing net. The synthesized composites demonstrated high strength as compared to standard hydrogels- Yung-module varied in the range of 80 to 300 kPa depending on the extent of PVA ac-etale matrix filling with hydrogel component. The materials showed high sorbability to water and water solutions. Study of swelling kinetics as compared to solvents of various nature (water, ethanol, sunflower oil ) was carried out.
