▎ 摘　　要

NOVELTY - Aqueous graphene dispersion comprises 1-15 wt.% dispersant, 0.05-0.5 wt.% graphene powder, 0-5 wt.% dispersion auxiliary agent and 10-50 wt.% anti-freezing component. The anti-freezing component is the product of the reaction of formic acid with metal oxides, hydroxides and/or carbonates. The dispersant is sodium polyaspartate, sorbitol ester, betaine, and/or quaternary ammonium compounds. The dispersion auxiliary agent is carboxymethyl cellulose salt. USE - The aqueous graphene dispersion is useful as substitute for general organic alcohol antifreeze, in electrolyte of battery systems, for the cooling medium of the battery system, and the antifreeze of the cooling system, as a heat exchange medium for clean energy devices and other energy storage devices, as a cooling medium for industrial production, as a raw material for the preparation of antifreeze hydrogels, and preparing thermal interface materials currently used in thermal interface (e.g. thermal conductive gel, thermal grease, and heat dissipation gasket) (claimed) and in the technical field of functional material preparation, rechargeable battery and printing technology catalytic organic synthesis. ADVANTAGE - The aqueous graphene dispersion has high stability under low temperature condition, and is non-toxic, harmless, low corrosion to various metal material and high molecular material, and has excellent energy storage effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous graphene dispersion.
