摘　　要：通过两步溶液聚合的方法制备了由丙烯酸单体(AA)与2-丙烯酰胺-2-甲基丙磺酸(AMPS)的共聚物和聚乙烯基吡咯烷酮(PVP)形成的具有互穿网络状结构(IPN)的新型聚合物水凝胶。并研究了共聚单体配比、PVP和交联剂对水凝胶电场响应性及力学性能的影响。探索了凝胶在电场作用下的弯曲机理。实验结果表明:此种具有IPN结构的凝胶具有较好的电场响应性和力学强度。当n(AA)∶n(AMPS)达到7∶3,w(PVP)=16%,w(交联剂)=0.05%时,水凝胶的综合性能达到最好。The novel hydrogels with interpenetrating polymer networks （IPN） were prepared by the two steps solution polymerization in which the copolymer of acrylic acid （AA） and poly （2 - acrylamido - 2 - methyl propane） sulphonic acid （AMPS） interacted with Polyvinylpyrrolidon （PVP）. It was studied that the influence of monomers proportions, PVP and cross- linker contents on the mechani- cal property and electronic responsivity. The mechanism of the electronic respoasivity was discussed. The results from the experiments indicated that the novel IPN hydrogels revealed very well electric field responsibility and mechanical property. When the proportion between n（AA） and n（AMPS） was 7：3, and the contents of PVP and cress linker separately were 16 wt% and 0.05 wt%, the general properties of hydrogels were optimum. Key words：
