Abstract

Core-shell microgels were synthesized by the grafting polymerization of N-isopropylacrylamide in the presence of the polyvinylamine using TBHP as the initiator. The poly(vinyl alcohol)/microgel composite hydrogels were also prepared by the solution mixing and the frozen-thawing method. The morphology and the inner-structure of the microgels were characterized by SEM and TEM experiments. The temperature-sensitive properties of microgels and composite hydrogels were also investigated. The results show that the microgels are spherical and have a core-shell structure. The microgels and composite hydrogels have a nearly same volume phase transition temperature and the composite hydrogels show a rapid phase transition behavior.
