Beschreibung
Zusammenfassung:	The invention discloses a graphite nanosheet in-situ growth boron nitride composite material and a preparation method thereof, and a heat-conducting polymer, and relates to the technical field of heat-conducting materials, a coupling agent modified boron nitride precursor, an amino modified graphite nanosheet and isocyanate are subjected to a reaction, sintering is performed in a protective gas atmosphere, and the graphite nanosheet in-situ growth boron nitride composite material is obtained. The graphite nanosheet in-situ growth boron nitride composite material is obtained. The invention aims to overcome the defects that in the prior art, graphite nanosheets are poor in insulativity and low in filling amount in a resin matrix; in order to solve the technical problems of low thermal conductivity of graphite nanosheets and low thermal conductivity of boron nitride, the invention provides the preparation method of the graphite nanosheet in-situ growth boron nitride composite material, and the obtained graphite
