▎ 摘　　要

NOVELTY - A graphene nanosheet material is prepared using a mixed gas of a carbon-containing gas and an auxiliary gas as a reaction gas source, by a plasma enhanced chemical vapor deposition (PECVD) method. Also claimed is, rapid preparation of graphene nanosheet material. USE - Graphene nanosheet material is used for preparing composite conductive paste (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite conductive paste, which comprises the graphene nanosheet material, a conductive polymer, a dispersant, a stabilizer and a solvent. The viscosity of composite conductive paste is 8000-50000 mPa.second, preferably 10000-25000 mPa.second, more preferably 15000-20000 mPa.second.
