▎ 摘  要

NOVELTY - The manufacturing process involves preparing either a graphene oxide dispersion having graphene oxide sheets or graphene oxide gel. A halogenating agent is introduced into the dispersion or gel to effect a chemical reaction to form a dispersion or gel of halogenated graphene sheets. A layer of the halogenated graphene dispersion or gel is dispensed and deposited onto a surface of a supporting substrate (216) under a shear stress condition. The fluid medium is removed from a wet layer (218) of halogenated graphene to form integrated layer of halogenated graphene. USE - Manufacturing process for integrated layer of highly oriented halogenated graphene sheets or molecules. ADVANTAGE - The manufacturing process is cost-effective process that produces thicker films of graphene-derived materials which exhibit a high dielectric breakdown strength, high dielectric constants, adequate mechanical strength, good thermal stability, and good chemical stability. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of a reverse roll-based layer transfer apparatus for producing highly oriented graphene oxide or graphene halide films.
