▎ 摘　　要

NOVELTY - Multicolor graphene antibacterial liquid comprises 0.01-5% graphene materials, 0-30% dye, 0.01-0.5% surfactant, 0.01-0.5% dispersant, 0.01-2% defoamer and remainder of water. USE - As multicolor graphene antibacterial liquid. ADVANTAGE - The liquid has excellent antibacterial performance, bright and adjustable colors, stable coloring performance and no drug resistance and its preparation process is simple, cost-effective, environmentally friendly and suitable for mass production and does not require too many special reaction conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the multicolor graphene antibacterial liquid, which involves (a) weighing graphene material and surfactant, adding the graphene material and surfactant to deionized water in order and performing ultrasonic dispersion to prepare a graphene material solution and (b) weighing and adding the dye, dispersant and defoamer to the graphene material solution prepared in step (a) and performing ultrasonic dispersion.
