Stand-up structure of graphene-like carbon nanowalls on CNT directly grown on…

Abstract. This work demonstrates the directly grown graphene-like carbon nanowall (GNW)–carbon nanotube (CNT)– polyacrylonitrile-based carbon fiber (CF) paper structure for use as a highly efficient supercapacitor. The CF was prepared by electrospinning, and was then treated by carbonization. The CNTs were directly grown on the CF paper by microwave plasma-enhanced chemical vapor deposit…
