POLYPHASE CARBON NANOSTRUCTURE INCLUDING DIAMOND NANOFLAKES EMBEDDED IN GRAPHENE SHEATHS AND METHOD FOR MANUFACTURING THE SAME

摘要

A polyphase carbon nanostructure may include graphene sheaths including at least one graphene layer; and diamond nanoflakes embedded in the graphene sheaths. The graphene sheaths may comprise multilayer graphene. Each graphene layer in the graphene sheaths may be aligned in parallel with the surface of the diamond nanoflake (111). The polyphase carbon nanostructure may further comprise a nanocrystalline diamond film positioned to surround the graphene sheaths. The polyphase carbon nanostructure has a high electric conductivity compared to a conventional nanocrystalline diamond film, which does not include graphite.
