ResumoAbstract In this study, silver/graphene oxide nanocomposites (Ag/GO) was synthesized via in situ method for antibacterial application. Silver/graphene oxide cotton fabric(Ag/GO/cotton fabric) was then synthesized via the dip ‐ coating method. The characteristics of GO, Ag/GO, and Ag/GO/cotton fabric were investigated with Fourier transform infrared spectroscopy, X‐ray diffraction, transmission electron microscopy, Raman spectroscopy, and energy ‐ dispersive X‐ray spectroscopy. The results showed that the distribution of silver particles with an average size of 17.41±4.55 nm was uniformed on the GO sheets. The Ag/GO mounted on the fabric surface after coated. Pseudomonas aeruginosa ATCC 27853 (P. aeruginosa) and Staphylococcus aureus ATCC 25923 (S. aureus) were used to test the antibacterial activity of Ag/GO and Ag/GO/cotton fabric by disk diffusion method. The results demonstrated that Ag/GO displayed high antibacterial activity with minimum inhibitor concentration (MIC) value was 2.0 and 50.0 μg/mL with P. aeruginosa and S. aureus , respectively. The Ag/GO/cotton fabric was able to against two types of bacteria P. aeruginosa and S. aureus with diameter of inhibition zone was 5.00 and 2.50 mm , respectively . The results had prospective applications in a lot of fields like clothing, mask, and protective gear.
