NOVELTY - The preparation method of highly elastic ternary composite hydrogel involves (i) dissolving acrylamide, initiator, dopant modifier, and crosslinking agent in a graphene oxide dispersion, stirring, and ultrasonically dispersing to obtain solution (a), (ii) leaving still the solution (a) to obtain polyacrylamide/graphene binary composite hydrogel, (iii) dissolving conductive polymer monomer in water, stirring, and ultrasonically dispersing to obtain solution (b), (iv) immersing polyacrylamide/graphene binary composite hydrogel in solution (b), and reacting. USE - Preparation of highly elastic ternary composite hydrogel (claimed). DETAILED DESCRIPTION - The preparation method of highly elastic ternary composite hydrogel involves (i) dissolving acrylamide, initiator, dopant modifier, and crosslinking agent in a graphene oxide dispersion, stirring and ultrasonically dispersing to obtain solution (a), (ii) leaving still the solution (a) at 60-80 degrees C for 12-24 hours to obtain polyacrylamide/graphene binary composite hydrogel, (iii) dissolving conductive polymer monomer in water, stirring, and ultrasonically dispersing to obtain solution (b), (iv) immersing polyacrylamide/graphene binary composite hydrogel in solution (b), reacting at 70-90 degrees C for 12-24 hours to obtain a reaction product, and (v) removing the reaction product, and washing the surface with deionized water.
