▎ 摘　　要

NOVELTY - Antibacterial composite material preparation involves adding hydrazine hydrate into graphene solution, and then adding N,N-dimethylformamide at 70 degrees C to obtain reduced oxidized graphene dispersion. The obtained reduced oxidized graphene dispersion is mixed with lithium chloride and bacterial cellulose powder with stirring at room temperature to obtain a red electro-spinning solution. The prepared red electro-spinning solution undergoes electro-spinning process to obtain three dimensional composite material, which is freeze dried. USE - Method for preparing antibacterial composite material (claimed) used as functional material for antibacterial mask. ADVANTAGE - The method prepares the antibacterial composite material in a simple and cost-effective manner with long service life. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic image of the antibacterial composite material.
