Abstract
A slurry of the graphene oxides comprises the graphene oxides and a solvent. The graphene oxides include a strong graphene oxide and a weak graphene oxide. The slurry can be used to make composite films of graphene oxides and graphene heat-conducting films. The slurry includes 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.
