▎ 摘  要

NOVELTY - A wrapped single-layer graphene oxide/carbon nanotube composite material comprises acidified single-layer graphene oxide nanosheets as a shell material and cut carbon nanotube as core material. The carbon nanotube as core material is wrapped using single-layer graphene oxide nanosheets to form dumpling-like structure or clam shell structure microparticles. USE - Wrapped single-layer graphene oxide/carbon nanotube composite material (claimed). ADVANTAGE - The wrapped single-layer graphene oxide/carbon nanotube composite material is highly dispersible, easy to reunite and agglomerate, easy to store and has excellent conductivity and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of wrapped single-layer graphene oxide/carbon nanotube composite material, which involves stripping graphene oxide solution using modified Hummers method, separating to obtain sediment (A) of single-layer graphene oxide, acidifying carbon nanotubes, ultrasonically cutting, separating to obtain sediment (B), dissolving or dispersing sediment (A) in a solvent to obtain solution (C), dissolving or dispersing sediment (B) in a solvent to obtain solution (D), mixing solution (C) and (D) to obtain mixture (E), mixing, aging, and separating.
