Objective:To analyze the disparity in antibacterial efficacy among various brands of graphene masks,with the aim of providing empirical support for manufacturers'product enhancement and evolution.Methods:In accordance with the standards WS/T 650-2019"Evaluation Method of Antibacterial and Bacteriostatic Effect"and GB/T 20944.3-2008"Evaluation of Antibacterial Properties of Textiles Part 3",a scientifically sound test model was established to assess the antibacterial performance of graphene masks using the"oscillation method".A zero-contact time sampling count was developed,and the coating plate was enumerated after agitation at 250r/min for 2 hours to calculate the antibacterial rate.The antibacterial performance of diverse manufacturers'graphene masks was juxtaposed.Results:Two manufacturers'graphene masks exhibited exceptional antibacterial efficacy,achieving an almost 100%antibacterial rate against Staphylococcus aureus and Escherichia coli.Conclusion:New graphene masks demonstrate superior bacteriostatic performance compared to traditional non-woven masks.
