▎ 摘　　要

NOVELTY - Preparing medical fabric graphene-based antibacterial coating assisted by a visible laser, comprises (1) dissolving nitrate in a graphene oxide aqueous solution, and uniformly stirring and mixing to obtain a uniform dispersion liquid, where the nitrate comprises silver nitrate, manganese nitrate, zinc nitrate, copper nitrate and/or ferric nitrate, (2) uniformly spraying the resultant uniform dispersion liquid on the surface of the medical fabric and drying, (3) continuously spraying a graphene oxide aqueous solution with the same volume as uniform dispersion liquid on the surface of the medical fabric dried in the resultant step, and (4) drying, rapidly scanning the medical fabric subjected to surface treatment by using 0.1-5 W visible laser for 0.5-2 minutes under the blowing of inert gas and obtaining the final product. USE - The method is useful for preparing medical fabric graphene-based antibacterial coating assisted by a visible laser. ADVANTAGE - The method: can quickly load the metal ions and metal complexes with antibacterial activity on the surface of different medical fabrics through the adhesion of graphene; and the obtained product has excellent antibacterial effect.
