▎ 摘　　要

NOVELTY - Bionic polydopamine modified graphene oxide conductive hydrogel comprises first network and a second network, the first network is a chemical cross-linking network, the second network is a dynamic network, and the second network is interspersed inside the first network. USE - Bionic polydopamine modified graphene oxide conductive hydrogel. ADVANTAGE - The bionic polydopamine modified graphene oxide conductive hydrogel has high compressive strength and tensile strength, and process is simple and easy to be industrialized. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a bionic polydopamine-modified graphene oxide conductive hydrogel, which involves: (A) dispersing the powdered dopamine microspheres in the graphene oxide solution, sonicating at room temperature, adding a PBS buffer solution with a pH of 7-8, a constant temperature water bath of 35-40 degrees C, and stirring to obtain a graphene oxide/polydopamine mixed solution; and (B) adding strong oxidant and Fe3+ salt to the graphene oxide/polydopamine mixed solution, magnetically stirring for 30-60 minutes, and freeze-drying to obtain a polydopamine-modified graphene oxide conductive hydrogel.
