NOVELTY - Preparing graphene/polybutylene succinate composite film involves lyophilizing polybutylene succinate and rapidly pulverizin, uniformly dispersing graphene in a solvent to form a mixed solution, pulverizing polybutylene succinate, adding to the mixed solution, stirring uniformly, covering graphene on the surface of the polybutylene succinate, drying the product, placing the product at 120 degrees C in a double roll. The coiler is subjected to a wrapping roller until a smooth and uniform surface is obtained, and then the sheet temperature is gradually lowered to 90 degrees C to obtain a graphene/polybutylene succinate composite film. The graphene/polybutylene succinate composite film has a lamellar structure and has a smooth shape surface structure, graphene/polybutylene succinate composite film includes a polybutylene succinate matrix and a graphene powder uniformly covering the surface of the polybutylene succinate substrate. USE - Method for preparing graphene/polybutylene succinate composite film. ADVANTAGE - The method enables to prepare graphene/polybutylene succinate composite film which has better elongation at break, and reduced the Young's modulus.
