Methods of making thermally conductive particles include mixing in a solvent carbon particles, a cationic surfactant or an amphoteric surfactant, a hydrolysis catalyst, and a silica precursor to result in mixed solution containing silica-coated carbon particles having volume resistivity of 1 x 106 &OHgr;-cm or more. Compositions comprising these particles and a polymeric medium, which, when molded, exhibit a combined property of thermal conductivity of at least 1 W/mK, and volume resistivity of at least 1 x 108 &OHgr;-cm. |
