▎ 摘 要
NOVELTY - A patterned graphene is prepared by forming graphite sheet target pattern into copper foil surface, heating, and growing. USE - Method for preparing patterned graphene used for flexible electrode, field effect transistor, sensor part or display device (all claimed). ADVANTAGE - The method has simple operation and high efficiency and quality product, solves complex and processing problems in the graphene device, and does not damage graphene.
