NOVELTY - This utility model claims a kind of boron nitride-graphene composite material structure, comprising two single layer nitride film (8, 10) and a single layer or multiple layer graphene film (9), wherein the graphene film (9) is located between the two of boron nitride film (8, 10). The composite material structure under the premise of not improving density of current carrier, obviously improves the electrical conductivity of the graphite.
