제목 Enhanced thermal conductivity of nanocomposites with vertically aligned silicon carbide sheets
초록 Thermally conductive epoxy composites have been prepared with three-dimensional (3D)-structured SiC sheets. Graphene oxide was finally transformed into SiC by a template-assisted chemical vapor deposition. Epoxy resin was infiltrated into the empty spaces of the SiC scaffold and the nanocomposites shows anisotropic thermal property with ultrahigh through-plane conductivity at a less than 5 vol % of SiC sheet content. A thermal percolation theory was proposed to explain the experimental results of SiC based nanocomposites. The chemcally bonded SiC nanoparticles at high temperature is a main factor to provide the highly thermal conductive composites.
