A phthalonitrile-based composite material has a thermally conductive filler. The thermally conductive filler is distributed in the phthalonitrile matrix resin, or the thermally conductive filler is distributed in a thermally conductive filler layer at least partially covering the surface of the phthalonitrile-based microspheres. The phthalonitrile-based composite material has good application prospects in the fields of heat conduction and heat conductive insulation.

Phthalonitrile-based composite material, preparation method therefor and use thereof
