NOVELTY - The in-line polymerization-solution phase-based preparation method of oxidized graphene/polybutylene succinate composite material involves (i) uniformly dispersing graphene oxide and polybutylene succinate in solvent (a), and dissolving polybutylene succinate to form a mixed solution, (ii) pouring solvent (b) into mixed solution, precipitating polybutylene succinate, (iii) removing the solvent (a) and solvent (b) in product, (iv) mixing the product with catalyst in a two-roll mill, and placing in a two-roll mill at 120 degrees C. USE - In-line polymerization-solution phase-based preparation of oxidized graphene/polybutylene succinate composite material (claimed). DETAILED DESCRIPTION - The in-line polymerization-solution phase-based preparation method of oxidized graphene/polybutylene succinate composite material involves (i) uniformly dispersing graphene oxide and polybutylene succinate in solvent (a), and dissolving polybutylene succinate to form a mixed solution, (ii) pouring solvent (b) into mixed solution, precipitating polybutylene succinate, where the polybutylene succinate is insoluble or sparingly soluble in solvent (b), (iii) removing the solvent (a) and solvent (b) in product, (iv) mixing the product with catalyst in a two-roll mill at 110 degrees C, placing in a two-roll mill at 120 degrees C, reducing the roller temperature to 90 degrees C, until the sample surface is smooth and uniform.
