▎ 摘　　要

NOVELTY - Preparing a graphene oxide-based interpenetrating network polymer hydrogel, comprising (1) dispersing graphene oxide in distilled water, adding acrylic acid, N-methylene bisacrylamide and ammonium persulfate, uniformly mixing, and initiating a polymerization reaction using ultraviolet light under the protection of nitrogen to obtain polyacrylic acid/graphene oxide interpenetrating network polymer hydrogel, (2) modifying the polyacrylic acid/graphene oxide interpenetrating network polymer hydrogel using concentrated ammonia water to obtain polyacrylic acid/amino modified graphene oxide interpenetrating network polymer hydrogel, and (3) mixing the polyacrylic acid/amino modified graphene oxide interpenetrating network polymer hydrogel with pyrrole, isopropanol, distilled water and hydrochloric acid uniformly, adding an ammonium persulfate aqueous solution under the condition of ice water bath, and reacting to obtain the final product. USE - The polymer hydrogel is useful in the flexible super capacitor electrode material (claimed). ADVANTAGE - The polymer hydrogel: has excellent flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a graphene oxide-based interpenetrating network polymer hydrogel electrode, comprising ultrasonically dispersing the polyacrylic acid/graphene oxide grafted polypyrrole interpenetrating network polymer hydrogel, acetylene black and PTFE in ethanol, coating the mixture on the nickel foam, carrying out vacuum drying for 6 hours at 60℃, and then pressing the mixture into a sheet under the pressure of 10 µPa to obtain the final product.
