▎ 摘 要
NOVELTY - Producing graphene, comprises: heating substrate and at least one feeder comprising seedlac, followed by contacting vapors of seedlac with the substrate; and cooling to produce the graphene. USE - The process is useful for producing graphene. ADVANTAGE - The process: provides the graphene which is impermeable, resistant to oxidation and hydrophobic; utilizes the substrate which has a corrosion rate of 0.02 mm/year, and an average water contact angle of 92-97.9 degrees (claimed); and is simple and economic. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) the graphene produced by the above process; and (2) the substrate comprising the graphene.
