Abstract: The present invention provides: a composite hydrogel including gelatin and reduced graphene oxide: a preparation method therefor; and a conduit or film manufactured using the same, wherein the composite hydrogel of the present invention overcomes the low conductivity and brittleness of a conventional functional hydrogel to maintain, through excellent elasticity and excellent ductility, high electrical conductivity and mechanical properties even if repeatedly compressed and bent, thereby being variously usable as a platform material for a conductive hydrogel, and thus can be effectively used, in a field requiring a conductive hydrogel, as an in vivo tissue engineering scaffold, a drug delivery system, a flexible body-implantable electrode, and an electronic device, which move a lot.

Abstract: Disclosed are an electrically conductive hydrogel having a graphene network and a method for fabricating the same. The electrically conductive hydrogel is fabricated by thermal annealing of granular hydrogel, and thus it has a porous structure, excellent electrical conductivity, and improved compressive modulus and yield stress. Accordingly, the electrically conductive hydrogel may be advantageously used in biomedical applications, such as scaffolds for tissue engineering, bioelectrodes, and biosensors.
