【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Fe³⁺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Fe³⁺/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 k Pa、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。更多还原

【Abstract】 In this paper,poly （acrylamide-acrylic acid） was used as the base hydrogel,and PPCH hydrogel was obtained by polymerization with Fe³⁺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 Fe³⁺/An molar ratio of 1.25,aniline infiltration for 5 min had a stress and strain at break of 180 k Pa 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.更多还原
