▎ 摘　　要

NOVELTY - Composite hydrogel comprises gelatin and reduced graphene oxide. USE - The composite hydrogel is used for conduit, and film (all claimed), and as platform material for conductive hydrogel, support for tissue engineering, drug delivery system, flexible human implantable type, electrode and electronic device. ADVANTAGE - The composite hydrogel can withstand repeated compression and bending due to its excellent elasticity and ductility, and retains high electrical conductivity and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the graphene oxide/gelatin composite hydrogel, which involves preparing a mixed solution containing gelatin, graphene oxide and a crosslinking agent, obtaining a crosslinked product by inducing crosslinking of the mixed solution, and reducing the crosslinked product.
