▎ 摘　　要

NOVELTY - A graphene dispersion liquid comprises graphene, dispersant and solvent composition. The dispersant is chosen from polyoxyethylene castor oil. The solvent is selected from water, methanol, ethanol, normal propyl alcohol, isopropanol, sec-butanol, n-butyl alcohol, isobutyl alcohol, tert-butyl alcohol, ethylene glycol, propylene glycol, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, isophorone, diacetone alcohol, two ethyl ketone, methyl propyl ketone, ethyl acetate, butyl acetate, isobutyl acetate, acetic acid hexyl ester, isohexyl ester and acetic acid n-heptyl ester. USE - Graphene dispersion liquid is used for conductive material, antistatic material, electromagnetic shielding material, electrode material of lithium ion battery and microwave-absorption material. ADVANTAGE - The graphene dispersion liquid has excellent electrical conductivity. DETAILED DESCRIPTION - A graphene dispersion liquid comprises graphene, dispersant and solvent composition.
