▎ 摘  要

NOVELTY - Preparing graphene dispersion liquid involves mixing and dispersing a dispersant with terpineol to obtain a terpineol dispersion medium containing a dispersant. The dispersant-containing terpineol dispersion medium is added to the graphene powder and uniformly mixed to obtain a graphene concentrate. The graphene concentrate is added to an organic solvent miscible with terpineol, and uniformly mixed to obtain a mixed solution. The mixed solution has a viscosity of 5-20 centipoise and a surface tension of 27-30 newton meter per meter, followed by mixing mixed solution with an auxiliary agent to obtain desired product. USE - Method for preparing graphene dispersion liquid used as conductive ink. ADVANTAGE - The method eanbles to preparing graphene dispersion liquid which has better dispersibility of graphene in terpineol and miscibility of terpineol as an organic solvent for alcohols, and controlls order of dispersion of graphene, and improves dispersion stability.
