Thermal conductivity and viscosity of graphite suspensions were experimentally studied by transient hotwire method and ARG2 method, respectively. By choosing different sonication time, thermal conductivity of graphite suspension at different volume fractions were obtained, as well as a thermal percolation behavior was observed. The viscosity shows opposite trend compared with thermal conductivity near percolation regime, which increases much faster before percolation than after percolation.
