Fabrication and Characterization of Graphene Nanofibers by Electrospinning Technique and Its Electrochemical Properties.

Graphene has proved to be superior material for its exceptional physicochemical properties. However engineering graphene macroscopic structures by manipulating microscopic structures has faced a great challenge. Towards this here we report a fabrication method of graphene nanofiber by using simple electrospinning method. Fourier transform infrared and Raman spectroscopic characterizations confirmed the transformation from GO to reduced graphene for the nanofiber material. Estimated surface area of this material is as high as 526 m²g-1 with pores having size around 20 nm. Specific-capacitance of these nanofibers for current-density of 1 Ag-1 is 144.2 Fg-1, which will be useful for the advancement of devices for storing energy.
