| Abstract: | PVA-P（AM-AAc）-Fe3+-Gly conductive hydrogel（PAFG） was prepared by free radical polymerization and freeze-thaw cycle method with polyvinyl alcohol（PVA），acrylamide（AM） and acrylic acid（AAc） as raw materials，ammonium persulfate（APS） as initiator，FeCl3 as crosslinking agent，glycerin（Gly） as antifreeze and water as solvent. The results showed that when the mass fraction of Gly was 50%，the tensile strength of PAFG was 409 kPa，the elongation at break was 934%，the freezing temperature was as low as -42 ℃，and the mass retention rate for 6 d was 90.3%；the conductivity of the prepared PAFG sensor was 0.38 S/m，the strain sensitivity was 3.13，and the cycle stability，reusability and durability were the best. |
