Title: Optical and Conductivity Properties of Films from Liquid-Phase Exfoliation of Natural Graphite
Published: May 15, 2009
Abstract: We experimentally determine the conductivity and optical transmittance of graphite layers, obtained from the liquid phase exfoliation of natural crystalline graphite. The measured transmittance values range from 0.9 to 0.97, comparable to the theoretical transmittance of graphene. In the low frequency limit the conductivity of the films follows the percolation model for two-dimensional networks. The solution processed graphene materials are attractive for applications as conductive transparent films and scalable graphene devices.
