Abstract: As a natural mineral,the application of anthracite associated graphite is limited by the ash content and defects when it is used as a material.A graphene-like material was obtained by heat treatment of anthracite associated graphite at low temperature without all kinds of chemical methods to remove ash from anthracite associated graphite or high temperature graphitization of anthracite associated graphite.The best quality graphene-like sheets were selected by Raman spectroscopy,TEM and optical microscopy to make a composite material with epoxy resin.The research showed that the thermal conductivity of the composite was 86.2% higher than that of pure epoxy resin when the weight fraction of graphene-like sheets was 20%.
