▎ 摘　　要

NOVELTY - Graphene compound antibacterial master batch, comprises 1-5 pts. wt. silver-plated graphene quantum dot, 90-100 pts. wt. polymer matrix, and 2-4 pts. wt. dispersant. The dispersant comprises a combination of dopamine and polyvinylpyrrolidone. USE - The master batch is useful in antibacterial products (claimed). ADVANTAGE - The master batch has antibacterial and antiviral effect, generates synergistic effect, good for improving dispersibility of silver-plated graphene quantum dot in the polymer matrix and compatibility with the polymer matrix, and improves the antibacterial, anti-virus and mechanical property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing graphene compound antibacterial master batch, comprising mixing silver-plated graphene quantum dot, polymer matrix, dopamine, polyvinylpyrrolidone and auxiliary agent, extruding and granulating to obtain graphene composite antibacterial master batch; graphene composite antibacterial fiber, obtained by spinning graphene composite antibacterial master batch; and graphene composite antibacterial film, obtained by blowing graphene composite antibacterial master batch.
