Summary: Graphene films have high electrical conductivity and good mechanical strength, making them ideal for use in supercapacitors. However, their low elastic deformation ability limits their application in stretchable supercapacitors. By combining graphene with a conductive polymer hydrogel, the resulting composite film exhibits improved ductility and higher specific capacitance. A proof-of-concept planar supercapacitor using this graphene-conductive polymer hydrogel composite film as electrodes retains excellent electrochemical performance even under stretching conditions.
