Abstract
Herein we report the incorporation of graphene into polyacrylonitrile (PAN)-based carbon nanofibers (CNFs) in order to improve the electrical conductivities of the CNFs. Graphene oxide (GO) was wrapped with PAN molecules to increase its dispersibility, which was verified by zeta potential measurements. The PAN-wrapped GOs were subsequently reduced in a nitrogen and acetylene atmosphere by simple heat treatment. Chemical reduction was confirmed by FT-IR and XRD analysis. These PAN-wrapped reduced GOs were mixed with PAN/DMF solutions and electrospun to produce nanofibers, which were then stabilized and carbonized at $1000^{\circ}C$. Finally, the electrical conductivity of the PAN-wrapped reduced GO-incorporated CNFs was characterized; a significant increase in electrical conductivity was observed due to graphene incorporation.
