▎ 摘　　要

NOVELTY - An article of graphene-modified polymeric foam comprises a graphene-based cell modifier and at least one polymer resin which is intermixed in the graphene-based cell modifier as a filler. The graphene-based cell modifier comprises a two-dimensional flake material with a thickness of 0.34-50 nm and a diameter of 0.1-50 microns. The graphene-based cell modifier is incorporated by infusing the graphene-based cell modifier in one or more of precursors for the polymer resin. USE - Article of graphene-modified polymeric foam for forming plastic material used in seat cushions of sofa, chair or car seats in mechanical, thermal, noise reduction, or sound absorption applications. Uses include but are not limited to refrigerator, freezer, building, water heater, automobile, buoyance in boats, acoustic sound-proof products, explosion suppression in fuel tanks of aircraft and vehicle, and furniture. ADVANTAGE - The article of graphene-modified polymeric foam has excellent mechanical properties, thermal performance, strength, electrical conductivity, thermal conductivity, barrier properties, and chemical resistance.
