NOVELTY - Performing cotton fabric antibacterial treatment method based on reduced graphene oxide and polyacid involves immersing the cotton fabric in 0.5-2 mol/L sodium hydroxide (NaOH) solution, ultrasonicating at 50℃ for 1-4 hours, taking out, washing with deionized water until neutral, and drying at 60-90℃. The 0.05-0.25 g of keggin-type polyoxometalates (POMs) is weighed, dissolved in 50-100 ml of deionized water, and obtained solution (A). The 0.25-1 g of graphene oxide (GO) is weighed, added 100 ml of deionized water, and then processed with a high-speed emulsifying shearer for 30 minutes to obtain solution (B). The cotton fabric is put into solution (A), and stirred with a magnetic stirrer for 0.5 hours at 40-70℃, then taken out and put into solution (B) to continue stirring for 0.5 hours, and cleaned with deionized water after the end. The 5 cycles are completed, then dried naturally to obtain graphene oxide-polyoxometalates (GO-POMs)-cotton fabric. USE - Method for performing cotton fabric antibacterial treatment method based on reduced graphene oxide and polyacid. ADVANTAGE - The method has a large number of sharp edges in RGO nanosheets and RGO has better electronic conductivity and is more destructive to bacterial cell membranes, and the RGO sheet can wrap the bacteria and isolate them from the medium they depend on for survival. The cell membrane channels of the bacteria are blocked and cannot reproduce by consuming nutrients, and eventually die, so that the cotton fabric has a certain antibacterial effect, and the addition of POMs, on the one hand, can be used as an intercalation agent to increase the distance between RGO sheets and improve the agglomeration phenomenon, and be used as a catalyst to make the antibacterial effect more excellent through the mutual synergy of RGO and POMs. DETAILED DESCRIPTION - Performing cotton fabric antibacterial treatment method based on reduced graphene oxide and polyacid involves immersing the cotton fabric in 0.5-2 mol/L sodium hydroxide (NaOH) solution, ultrasonicating at 50℃ for 1-4 hours, taking out, washing with deionized water until neutral, and drying at 60-90℃.

The 0.25-1 g of graphene oxide (GO) is weighed, added 100 ml of deionized water, and then processed with a high-speed emulsifying shearer for 30 minutes to obtain solution (B). The cotton fabric is put into solution (A), and stirred with a magnetic stirrer for 0.5 hours at 40-70℃, then taken out and put into solution (B) to continue stirring for 0.5 hours, and cleaned with deionized water after the end. The 5 cycles are completed, then dried naturally to obtain graphene oxide-polyoxometalates (GO-POMs)-cotton fabric. The GO-POMs-cotton fabric immersed into the sodium borohydride (NaBH4) solution for reduction, and taken out after 1 hour, and washed with deionized water until the solution is clear, and dried at 80-90℃ to obtain reduced graphene oxide-polyoxometalates (RGO-POMs)-cotton fabric.
