摘　　要：本文采用聚(丙烯酰胺-丙烯酸)作为基底水凝胶,在经苯胺单面渗透后用Fe^(3+)氧化聚合得到PPCH水凝胶。主要考察了PPCH水凝胶的导电性、力学性能和应变传感性能,结果表明:在Fe^(3+)/An摩尔比为1.25、苯胺渗透5 min下得到的PPCH水凝胶,断裂应力和应变分别为180 kPa、553%,此时电导率为0.269 S/m;在0-400%应变范围内,PPCH水凝胶的灵敏度(GF)最高值为6.31;基于PPCH水凝胶的柔性应变传感器能够用于对人体运动的监测。In this paper,poly(acrylamide-acrylic acid)was used as the base hydrogel,and PPCH hydrogel was obtained by polymerization with Fe^(3+) after single-sided infiltration of aniline.The conductivity,mechanical properties and strain sensing properties of PPCH hydrogel were mainly investigated.The results showed that the PPCH hydrogel obtained at Fe^(3+)/An molar ratio of 1.25,aniline infiltration for 5 min had a stress and strain at break of 180 kPa and 553%,respectively,and the conductivity was 0.269 S/m.The maximum sensitivity(GF)of PPCH hydrogel was 6.31 in the range of 0-400%strain.The flexible strain sensor based on PPCH hydrogel can be used to monitor human motion.
