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.
