▎ 摘  要

NOVELTY - A graphene oxide-modified foamed material comprises 70-100 pts. wt. polylactic acid, 5-30 pts. wt. polycaprolactone, 1-10 pts. wt. graphene oxide, 2-20 pts. wt. composite foaming agent, 1-7 pts. wt. surface active agent, 4-6 pts. wt. organic nano-nucleating agent, and 1-2 pts. wt. foaming additive. The graphene oxide-modified foamed material has dielectric constant of 2-9 F/m, conductivity of 0.1-0.8 S/m, apparent density of 0.1-0.9 g/cm3, compressive strength of 5-9 MPa, impact strength of 10-85 KJ/m2 and average cell diameter of 100-300 mu m. USE - Graphene oxide-modified foamed material (claimed). ADVANTAGE - The graphene oxide-modified foamed material has excellent mechanical properties, heat resistance, and controlled density, and is prepared by simple and economical process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide-modified foamed material, which involves mixing raw materials, drying, extruding, granulating, and foaming obtained masterbatch.
