▎ 摘 要
NOVELTY - Graphene/epoxy resin composite material having weakly negative dielectric constant is claimed. The composite material is prepared by mechanical ball milling epoxy resin as matrix, graphene as functional body, and hot pressing molding. USE - Used as graphene/epoxy resin composite material having weakly negative dielectric constant. ADVANTAGE - The material has simple preparation process, and low cost; and is suitable for industrial production.
