Abstract: The hydrogel was prepared by free radical polymerization and freeze-thaw cycle using hydroxypropyl acrylate, ι-carrageenan,  polyvinyl alcohol and calcium chloride as raw materials. We tested and analyzed the mechanical property,  self-recovery property,  swelling property,  self-healing property,  anti-fatigue property and the conductivity property of the hydrogel. The results show that the hydrogel has high mechanical strength, the fracture stress is 625.77 kPa, the fracture elongation is 604.48%, the swelling rate of hydrogel is low, and has excellent self-recovery property,  anti-fatigue property  and  conductivity property.

Key words: hydroxypropyl acrylate,  ,  , ι-carrageenan,  , polyvinyl alcohol, hydrogel, multifunction
