Method of producing highly dispersed graphene organic dispersion and application thereof

摘要

A highly dispersed graphene organic dispersion and an application thereof are provided. A mixture is firstly provided, which includes a graphite material and an organic solvent. And then, the mixture is subjected to a peeling process at high temperature and high pressure, thereby obtaining the highly dispersed graphene organic dispersion. The highly dispersed graphene organic dispersion contains 75% or more of a single-layered graphene.

1. A method of producing highly dispersed graphene organic dispersion, comprising:
providing a mixture, wherein the mixture includes a graphite material and an organic solvent, and a solids content of the mixture is 0.001 mg/ml to 10.0 mg/ml; and performing a peeling process to the mixture, wherein the peeling process includes:
performing a peeling step to the mixture in a closed reaction tank at a first temperature for 10 minutes to 4 hours, so as to form a graphene solution, wherein the first temperature is more than 5° C. to 50° C. above a boiling point of the organic solvent; andperforming a dispersing step to the graphene solution at a second temperature, so as to form the highly dispersed graphene organic dispersion, wherein the second temperature is 5° C. to 40° C., and the highly dispersed graphene organic dispersion contains 75% and more of a single-layered graphene.
