▎ 摘　　要

NOVELTY - Preparing graphene/nano microcrystalline cellulose aqueous dispersion, comprises dispersing nano microcrystalline cellulose in water to obtain a certain solid content graphene dispersion system A, dispersing graphene in water to obtain a certain solid content dispersion system B, dispersing the dispersion system A in the dispersion system B, regulating the nano microcrystalline cellulose and graphene content, adjusting system pH value to a certain value to obtain A/B aqueous phase composite dispersion, placing the A/B aqueous phase composite dispersion in ultrasonic cell crusher and subjecting to ultrasonic treatment for a certain time under certain power to obtain final product. USE - The method is useful for preparing graphene/nano microcrystalline cellulose aqueous dispersion. ADVANTAGE - The method: utilizes nano microcrystalline cellulose which improves dispersion stability of aqueous graphene, achieves a synergistic effect, and avoids stacking of simple process.
