中文摘要：

以过硫酸铵为引发剂通过一步溶液聚合制备了由化学交联的聚丙烯酰胺(PAM)与聚乙烯吡咯烷酮(PVP)贯穿形成的PAM/PVP半互穿网络(semi-IPN)凝胶,着重研究了凝胶的机械性能。红外光谱、热重分析及拉伸实验分析可知PAM与PVP之间存在氢键作用。拉伸实验表明:在PAM中引入PVP,凝胶拉伸强度明显提高,m(PVP)/m(AM)=7.51%时制备的PAM/PVP semi-IPN凝胶拉伸强度比单纯化学交联的PAM增大64.67%;当AM=6mol/L,n(MBA)/n(AM)=1.67×10-4,m(PVP)/m(AM)=7.51%时,制备的凝胶机械性能较好,拉伸强度达到1.84MPa,断裂伸长率可达3322%;随着含水率增加,凝胶拉伸强度及断裂伸长率均有所降低。
