NOVELTY - Preparation of degradable graphene-polybutylene succinate composite foam, involves mixing 1-30 parts mass monolayer graphene oxide dispersion having a size of 1-50 microns and a carbon/oxygen ratio of 3-6, and 1-10 parts mass foaming agent to obtain material (A), banburying 200 parts mass polybutylene succinate, 0.1-6 parts mass maleic anhydride, and 0.1-3 parts mass calcium carbonate in an internal mixer at 75-100 degrees C to obtain material (B), banburying materials (A,B) at 95-220 degrees C, adding to a mold, and foaming at 95-120 degrees C for 2-15 minutes, and then at 120-200 degrees C for 5-20 minutes. USE - Preparation of degradable graphene-polybutylene succinate composite foam. ADVANTAGE - The method enables simple and easy preparation of degradable composite foam having excellent elasticity, heat resistance, and strength.
