Abstract

Silica coated flake graphites as a thermally conductive and electrically insulating filler for epoxy resin composites were fabricated with surfactants and acid–base catalysis by a flexible sol–gel method. The volume resistivity of the silica coated graphite increased from 184 Ω m of the original graphite to 6391 Ω m because the silica coating provides an electrically insulating property. The influences of the silica coated graphite fraction, particle size and surface treatment on the performance of the hot-pressed composites were investigated. The thermal conductivity of the composites increased with incremental of the fillers concentration, as well as with decreasing of the filler size. The silica coated graphite/epoxy resin composites presented a high volume resistivity of 3.11 × 109 Ω m and thermal conductivity of 3.08 W m−1 K−1 at 50 wt% filler loading ratio. The research sets the way toward the choice of a proper treatment for improving the thermal conductivity and electrical insulation of highly filled epoxy matrix composites.
