▎ 摘  要

NOVELTY - The method comprises (S1) dispersing graphene in absolute ethanol at a ratio of 0.6 mg/ml to obtain a graphene solution, (S2) dispersing the silver powder into absolute ethanol according to the ratio of 120 mg/ml, and placing it in an ultrasonic cleaner to oscillate to obtain a silver solution, (S3) placing the graphene solution in an ultrasonic cleaner to mix with the silver solution, and starting the ultrasonic cleaner again to vibrate to obtain a mixed solution, and (S4) adding the mixed solution in a magnetic stirrer, stirring it into a semi-colloid, and placing the semi-colloid mixture on a high-energy ball mill for ball milling, placing the ball-milled composite powder in a vacuum drying oven for drying to obtain a composite powder of graphene and silver. USE - Method for preparing graphene silver powder mixture, which is useful in biological medicine and drug delivery. The graphene silver mixture is useful as a material learning material, micro-nano processing material, energy material and biological medicine material. ADVANTAGE - The method is simple and cost-efficient , and suitable for mass production.
