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…
Abstract. Low operating electric field and stable emission current have been achieved on ordered carbon nanotube (CNT)-ZnO heterojunction arrays. Pyramid-like micropatterns were firstly prepared via capillarity-driven self-assembly from aligned CNTarrays, ZnO nanowires were subsequently grown via vapor-phase transport (VPT) method. Based on the effect of geometrical structure, low turn-on and …
