▎ 摘  要

NOVELTY - Preparation of graphene additive comprises preparing graphene oxide dispersion with of 1 mg/mL concentration, adding hydrazine hydrate, adding mixture into carrier, vibrating mechanically with seal for 3-5 minutes, subjecting to ultrasonic treatment, placing mixture in reaction kettle, subjecting to hydrothermal reaction under protective gas to obtain mixed hydrogel, refrigerating hydrogel for 12-24 hours, and lyophilizing refrigerated hydrogels at - 50-- 15 degrees C and less than or equal to 10 Pa for 24-48 hours. USE - Method for preparing graphene additive used for conductive coating (claimed). ADVANTAGE - The method has good heat conducting effect, and avoids agglomeration of graphene.
