Shape-alterable and -recoverable graphene/polyurethane bi-layered composite film for supercapacitor electrode

---

Abstract.
In this paper, a graphene/shape-memory polyurethane (PU) composite film, used for a supercapacitor
electrode, is fabricated by a simple bonding method. In the composite, formerly prepared graphene paper
is closely bonded on the surface of the PU slice, forming a bi-layered composite film. Based on the good
flexibility of graphene paper and the outstanding shape holding capacity of PU phase, the resulting
composite film can be changed into various shapes. Also, the composite film shows excellent
shape recovery ability. The graphene/PU composite film used as the electrode maintains a satisfactory
electrochemical capacitance of graphene material and there is no decay in the specific capacitance after
long-cycle testing, making it attractive for novel supercapacitors with special shapes and shape-memory
ability.

Keywords: Graphene paper, Shape-memory polyurethane, Composite, Supercapacitor
