▎ 摘　　要

NOVELTY - The composite material has a boron nitride film (8) which is arranged on a graphite alkene film (9). The graphite alkene film is arranged on a boron nitride film (10). The boron nitride films (8,10) and the graphite alkene film are connected together by the pressing process. The thickness of the boron nitride films (8,10) is 0.5-500 nm. An transparent substrate is provided for covering one of the boron nitride films (8,10). USE - Boron nitride-graphene composite material for electrode (claimed). ADVANTAGE - The boron nitride-graphene composite material can be effectively prepared without increasing the carrier density. Hence, conductivity of the boron nitride-graphene composite material can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing boron nitride-graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the boron nitride-graphene composite material. Boron nitride films (8,10) Graphite alkene film (9)
