Beschreibung
Zusammenfassung:	The invention discloses a flexible graphene-diamond composite thermal interface material and a preparation method and application thereof, and belongs to the technical field of composite thermal interface materials.The preparation method comprises the steps that a microwave plasma chemical vapor deposition method is adopted, liquid micromolecules serve as a carbon source and a nitrogen source and are deposited on the surface of silicon or graphite, and the flexible graphene-diamond composite thermal interface material is obtained. Then, organic polymer spin coating is carried out, so that organic polymers permeate into internal pores of the graphene-diamond composite film, and the graphene-diamond composite film is obtained; the heat conductivity of the graphene-diamond composite thermal interface material is larger than or equal to 90 W/(m.K), the heat conductivity of the flexible graphene-diamond composite thermal interface material is larger than or equal to 10 W/(m.K), the bending radius is larger than or
