    Abstract

    Graphene/carbon nanofilament (G/CNF) hybrids were synthesized by an electrochemical post-treatment of as-prepared CNFs. After the mild electrochemical exfoliation, the surface of CNFs was partially exfoliated and converted into graphene nanosheets. Field emission measurements for G/CNF hybrids show a low turn-on voltage of 1.34 V/mu m and a high field enhancement factor (beta) of 4930. The extraordinary b is attributed to the strong edge emitter effect of graphene nanosheets based on their high aspect ratio and high surface area. (C) 2017 Published by Elsevier B.V
