▎ 摘　　要

NOVELTY - Carbon nanotubes and graphene microchip are processed with concentrated sulfuric acid and nitric acid, respectively, to form mixture (a). The mixture (a) and acryloyl chloride monomer are atom-transfer-radical-polymerized in presence of azobisisobutyronitrile as an initiator, to obtain pale yellow solution of hydroxylated nanotubes-grafted polypropylene chloride. The hydroxylated nanotubes-grafted polypropylene chloride is grafted, to obtain three-dimensional carbon nanotube/graphene hybrid material. USE - Production of three-dimensional carbon nanotube/graphene hybrid material (claimed). ADVANTAGE - The method enables environmentally-friendly production of three-dimensional carbon nanotube/graphene hybrid material with excellent repeatability and high yield within short period of time, by simple method.
