摘要：
In this study, graphite nanosheets were prepared by powdering expanded graphite with sonication in aqueous alcoholic solution. Epoxy resin/graphite nanosheet nanocomposites were fabricated and their electrical and mechanical properties were investigated. The results revealed that graphite sheets 30-80 nm in thickness could be effectively dispersed within the epoxy resin. The percolation threshold of epoxy resin/graphite nanoparticles was about 0.015, much lower than that of composites with conventional graphite. However, tensile strength, impact strength, and elongation at break of the composites, with increase in graphite nanosheets content, were all sacrificed.
