▎ 摘  要

NOVELTY - A graphene release agent comprises 2-methoxy ethanol, N-methyl benzylamine, chlorobenzyl amine, 3-phenylpropyl amine, 2-fluoro benzylamine, tetraethoxy titanium, pyrrolidine, piperidine, benzoyl chloride and pyridine. USE - Graphene release agent used for graphene dispersion liquid for manufacturing graphene film (all claimed). Uses include but are not limited to transparent electrode used for flat-panel display, touchscreen, antistatic film, heat-resistant element, secondary battery, hydrogen storage agent and lightweight structure material. ADVANTAGE - The graphene film is manufactured with improved yield using graphene release agent. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene dispersion liquid, which comprises a graphene and the graphene release agent; and (2) manufacture of a graphene film, which involves mixing the graphene release agent and graphite powder to obtain graphite suspension, treating suspension with ultrasonic waves, peeling graphene and recovering dispersion liquids.
