NOVELTY - The preparation method of graphene/polybutylene succinate composite material involves (i) dissolving polybutylene succinate in a solvent (a) to form a solution (a), (ii) dispersing graphene in solvent (a) to form a solution (b), (iii) mixing solution (a) and solution (b) to form a mixed solution, (iv) pouring mixed solution into a solvent, precipitating polybutylene succinate, (v) removing the solvent (a) and solvent (b) in reaction product, (vi) roll-coating the product by a two-roll mill, and gradually reducing the roller temperature. USE - Preparation of graphene/polybutylene succinate composite material (claimed). DETAILED DESCRIPTION - The preparation method of graphene/polybutylene succinate composite material involves (i) dissolving polybutylene succinate in a solvent (a) to form a solution (a), (ii) uniformly dispersing the graphene in solvent (a) to form a solution (b), (iii) uniformly mixing solution (a) and solution (b) to form a mixed solution, (iv) pouring mixed solution into a solvent, precipitating polybutylene succinate, where polybutylene succinate is insoluble or sparingly soluble in solvent (b), (v) removing the solvent (a) and solvent (b) in reaction product, (vi) roll-coating the product by a two-roll mill at 120 degrees C, and gradually reducing the roller temperature to 90 degrees C, until the surface of film is smooth and uniform.
