▎ 摘　　要

NOVELTY - A polycaprolactone macromolecular degradable material is obtained by modifying polycaprolactone degradable macromolecule material with graphene and magnesium oxide. USE - Polycaprolactone macromolecular degradable material is used in plastic film applications. ADVANTAGE - The economical polycaprolactone macromolecular degradable material has excellent mechanical property, and can be prepared by increasing dispersibility of the reinforced phase in polycaprolactone matrix.
