| description | The invention relates to the technical field of heat-conducting interface materials, in particular to a silver/graphene composite heat-conducting interface material and a preparation method thereof. The preparation method of the silver/graphene composite heat-conducting interface material comprises the following steps: A, carrying out surface pretreatment on a copper base material; B, depositing graphene at the position, subjected to surface pretreatment, of the copper base material; C, soaking the copper base material deposited with the graphene in a silver salt solution for a replacement reaction, replacing copper atoms on the outer layer of the copper base material with silver, and obtaining a composite initial product of silver and graphene; and D, cleaning the surface of the composite head product of silver and graphene prepared in the step C. The preparation method of the silver/graphene composite heat-conducting interface material is simple in preparation process and mild in reaction, the heat-conducti |
