NOVELTY - Preparing a thermally conductive graphite sheet involves dispersing graphite raw material and magnetic particles in a solvent to form a graphite slurry, where the graphite raw material is graphite oxide and/or graphene oxide, and the main component of the solvent is water, preferably deionized water. The graphite slurry is deposited on a substrate, placed in a magnetic field environment, heated and then dried to form a coating layer. The dried coating layer is subjected to carbonization treatment and graphitization to obtain a heat conductive graphite sheet. USE - Method for preparing thermally conductive graphite sheet. ADVANTAGE - The method enables to prepare thermally conductivity graphite sheet, which has improved performance.
