▎ 摘　　要

NOVELTY - Preparing tannic acid-reduced graphene oxide conductive hydrogel, comprises dispersing tannic acid-reduced graphene oxide into water to obtain tannic acid-reduced graphene oxide suspension, dissolving carboxymethyl cellulose and acrylic acid into the tannic acid-reduced graphene oxide suspension, adding iron(III) chloride, and mixing to obtain first mixed solution, cooling the first mixed solution to 0-4℃, adding initiator into the first mixed solution, and mixing to obtain second mixed solution, injecting the second mixed solution into a mold and molding for 12-200 seconds to obtain final product. USE - The tannic acid-reduced graphene oxide conductive hydrogel is useful for biosensing field. ADVANTAGE - The method: produces degradable, self-repairing, adhesive and conductive hydrogel; and utilizes raw material, which has excellent biocompatibility, low cost, safety and non-toxicity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for tannic acid-reduced graphene oxide conductive hydrogel prepared by above method.
