For biomimetic applications, an artificial material is needed to be self-healing, electroactive and bioapplicable. Herein we report a strategy to build a graphene-poly(N,N-dimethylacrylamide) (PDMAA) cross-linking structure based on graphene networks. The obtained hydrogel exhibits good neural compatibility, high conductivity, low impedance and efficient near-infrared-triggered photothermal self-healing behaviour owing to its unique 3-dimensional graphene-PDMAA cross-linking networks. The results indicate that the graphene-PDMAA hydrogel has potential for application as an artificial tissue.
