摘要: Semi-IPN hydrogels (based on cross-linked polyacrylamide having poly(N-isopropylacrylamide) (PN1PAAm) inside) were synthesized and their properties, such as swelling ratio compressive elastic moduli, studied at several temperatures. Equilibrium ratios of semi-IPN markedly decreased due to the presence less hydrophilic PNIPAAm chains. The presented greater modulus when compared PAAm hydrogel. effect was explained being an additional contribution chains, which collapsed around networks, modulus. It pointed out that networks support According results in this work, present better mechanical properties than hydrogel, mainly chains are a state.
