【摘要】 基于水凝胶的传感器因其仿生结构、性能以及生物相容性受到越来越多的关注，而制备兼具优异力学性能和高导电性能的水凝胶仍是业内的挑战.通过将羧甲基纤维素钠和氯化钠引入聚丙烯酰胺网络，形成半互穿网络（Semi-IPN），制备出一种断裂应变为1 100%、电导率达6.03 S·m^-1的高拉伸离子导电水凝胶.该水凝胶具备良好的防冻能力，在-20℃下仍能保持良好的导电性和拉伸性.更多还原

【Abstract】 Hydrogel-based sensors have attracted increasing attention due to their biomimetic structure,properties,and biocompatibility.However,fabricating hydrogels that simultaneously possess excellent mechanical properties and high conductivity remains a challenge.By incorporating sodium carboxymethyl cellulose and sodium chloride into a polyacrylamide network,a Semi-IPN has been constructed,resulting in a highly stretchable ionic conductive hydrogel with a fracture strain of 1 100% and a conductivity of 6.03 S·m^-1.This hydrogel also exhibits excellent anti-freezing properties,maintaining both conductivity and stretchability at temperatures as low as-20 ℃.更多还原
