▎ 摘　　要

NOVELTY - Preparing high-strength and strain-responsive graphene oxide conductive hydrogel comprises (i) adding 1-6 pts. wt. chitosan, 0.01-4 pts. wt. chitosan-modified graphene oxide and 10-30 pts. wt. acrylamide monomers into the container at room temperature, and adding 50-250 pts. wt. solvent and mixing to form a uniform solution; (ii) under room temperature conditions, adding 5-20 pts. wt. hyperbranched polysiloxane containing epoxy groups, vinyl group and alkyl group and 0.01-0.06 pts. wt. initiator into the obtained solution, uniformly stirring, and reacting at 30-60 degrees C for 2-36 hours to obtain hyperbranched polysiloxane crosslinked composite hydrogel; and (iii) soaking composite hydrogel in a sodium chloride solution for 1-24 hours. USE - The high-strength and strain-responsive graphene oxide conductive hydrogel is useful in wear-resistant electronic device (claimed). ADVANTAGE - The hydrogel has superior mechanical properties, excellent strain conductive response characteristics, and is suitable for market promotion and application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: a high-strength and strain-responsive graphene oxide conductive hydrogel prepared by the above method.
