NOVELTY - Enhancing filming performance of graphene oxide modified biological fillers involves dissolving the silane coupling agent in an ethanol-aqueous solution to prepare an ethanol aqueous solution of the silane coupling agent, immersing the filler substrate in the ethanol aqueous solution of the silane coupling agent at room temperature and drying, weighing certain amount of graphene oxide powder, dispersing in deionized water under stirring, and performing ultrasonic treatment to obtain a uniform dispersion of 0.1-3g/L, placing the filler substrate in the graphene oxide dispersion liquid, dipping and drying under pressure driving. The graphene oxide is deposited on the surface of the filler substrate to form a dense layer. USE - Method for enhancing filming performance of graphene oxide modified biological fillers. ADVANTAGE - The method enables to enhance filming performance of graphene oxide modified biological fillers high hydrophilicity, improves compatibility of graphene oxide and biological filler, enhances interface bonding strength, increases surface energy of filler substrate and improves the film hanging speed and the film hanging amount.
