Fabrication of Graphene Nanofiber from Graphene Oxide By Ice Template

We reported the fabrication of highly ratio surfance area graphene nanofibers (GNFs) by ice template method from two-dimensional graphene oxide to one or one point five dimensional graphene nanofibers. GNFs exhibited good structural stability, high surface area, and electrical conductivity twice that of carbon nanotube aggregates. It’s used as electrode materials in supercapacitor, exhibited high ratio capacitance and energy density in a wide range of high power density and excellent cycling stability, higher than carbon nanotubes.
