▎ 摘　　要

NOVELTY - Method for preparing low-foam high-conductivity graphene aqueous slurry involves (a) dissolving non-ionic dispersant in deionized water at first temperature until the solution is completely clear, (b) using a first liquid phase peeling device to peel the pre-dispersion liquid at low speed for a first predetermined time period at a third temperature, where the third temperature is less than or equal to the cloud point of the non-ion dispersant and more than 0degrees Celsius, (c) using the first liquid-phase peeling equipment to peel off the dispersion after peeling at a low rate for a second predetermined time for a high speed at a second preset time period, (d) using second liquid phase peel device to further peel the graphene aqueous slurry after the peeling, and (e) obtaining the low foam high-coagulant graphene-tetrahydro-aqueous slurry. USE - The method is useful for preparing method of low-foam high-conductivity graphene aqueous slurry used in surfactant and graphene material. ADVANTAGE - The method enables to prepare low foam high-conductivity graphene aqueous slurry that has high conductivity, less air bubble, and not easy to settle. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a low-foam high-conductivity graphene aqueous slurry.
