▎ 摘 要
NOVELTY - Preparing graphene/carbon nano tube composite material comprises (1) manufacturing stage graphene oxide, (2) providing graphene acid material into to the carbon nanotube (CNT) fiber, (3) adding graphene acid bonding phase of the CNT fiber. USE - The method is useful for preparing graphene/carbon nano tube composite material (claimed). ADVANTAGE - The method: is simple. The material: has electrical conductivity; has dissipativity; has thermal conductivity; has high strength; and has no acidification.
