Progress in preparation of interpenetrating polymer network hydrogels and their application in adsorption
摘要
Abstract
Interpenetrating polymer network (IPN) hydrogels have attracted great attention mainly due to their wide applications in separation processes. The recent design concepts of IPN hydrogels, including sequential IPN,simultaneous IPN and semi-IPN,based on polysaccharides (such as chitosan,alginate,starch,and other polysaccharides),protein (such as gelatin,collagen,silk fibroin and soy protein) and synthetic polymers (ionic and nonionic polymers) are introduced. Moreover, semi-IPN and IPN hydrogels as adsorbent used in separation of dyes and heavy metal ions are reviewed. In order to improve biocompatibility,swelling rate and mechanical properties,synthetic polymers composed of natural polymers are used to fabricate IPN hydrogels. IPN hydrogels are endowed with very fast kinetics and high sorption capacity for sorption of dyes and heavy metal ions compared with single network hydrogels. Future research could be highly efficient IPN hydrogels,such as ion-imprinted IPN hydrogels and macroporous IPN composites cryogels,in improving specific surface area and selective adsorption.关键词
