▎ 摘 要
NOVELTY - A conductive film is prepared by depositing a layer of nickel on clean and dry glass substrate, chemical vapor depositing graphene layer at graphene thickness of 50-100 mu m, carbon source methane, mixed gas hydrogen and helium gas, cooling to room temperature, cleaning, removing surface nickel film layer, and drying. USE - Method for preparing conductive film (claimed). ADVANTAGE - The method features low production cost, simple preparation and high efficiency.
