Antibacterial Electroconductive Composite Coating of Cotton Fabric

Graphene oxide (GO) was deposited on a cotton fabric and then thermally reduced to reduced graphene oxide (rGO) with the assistance of L-ascorbic acid. The GO reduction imparted electrical conductivity to the fabric and allowed for electrochemical deposition of Ag degrees particles using cyclic voltammetry. Only the Ag degrees/rGO composite coating imparted antibacterial properties to the fabric against Escherichia coli and Staphylococcus aureus. Ag degrees/rGO-modified fibers were free of bacterial film, and bacterial growth inhibition zones around the material specimens were found. Moreover, Ag degrees/rGO-modified fabric became superhydrophobic with WCA of 161 degrees.

Automated summary

Graphene oxide was deposited and thermally reduced on cotton fabric, leading to electrical conductivity. The resulting fabric was then used for electrochemical deposition of silver particles. Only the silver/reduced graphene oxide composite coating exhibited antibacterial properties and superhydrophobicity.
