NOVELTY - Graphene oxide slurry comprises aromatic compound and graphene oxide in a mass ratio of (1-10):100. USE - Graphene oxide slurry for graphene oxide film (claimed). ADVANTAGE - The graphene oxide slurry has high density of graphene oxide film, sheet layer of the film is good, compact, the bonding force of the sheet layer is good and the prepared graphene heat conducting film of heat conducting performance is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a method for preparing graphene oxide slurry, which involves configuring the graphene oxide dispersion, and dispersing the aromatic compounds in the graphene oxide dispersion until the aromatic compounds are uniformly dispersed; 2. a graphene oxide film, comprises graphene oxide and the aromatic compound filled in graphene oxide sheet defect; and 3. a preparation method of graphene oxide film, which involves preparing the graphene oxide slurry containing aromatic compounds, coating the graphene oxide slurry on the substrate to form a wet graphene oxide slurry film, and drying and peeling the wet graphene oxide slurry film to obtain a high-density graphene oxide film.
