Abstract
Provided are a slurry of graphene oxides with different degrees of oxidation, a composite film of graphene oxides, and a graphene heat-conducting film. The slurry of the graphene oxides comprises the graphene oxides and a solvent, and the graphene oxides include a strong graphene oxide and a weak graphene oxide, wherein the slurry comprises two graphene oxides with different degrees of oxidation, which can increase a carbon content in the graphene oxide per unit mass, so that the finally obtained graphene heat-conducting film has more carbon.
