Synthesis of graphene oxide ‐ based silver cotton fabric application for antibacterial activity

Abstract

AbstractIn 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.
