Synthesis and Characterization of Temperature and pH Sensitive Hydrogel

摘要: 乙烯基吡咯烷酮与丙烯酸共聚物／聚丙烯酸β-羟基丙酯互穿网络水凝胶具有温度及PH双重敏感特性。经验证，在蒸馏水中，聚丙烯酸β－羟基丙酯与丙烯酸间存在络合作用，在缓溶液中，没有这样络合作用。

Abstract: The new IPN hydrogel poly(NVP co AA)/Poly(HPAT) was prepared by using interpenatrating polymer networks(IPN) technique. The temperature and pH sensitivity of this hydrogel was studied. In distilled water,the swelling ratio(SR) of this hydrogel slumps s
