Electrochemical characterization of reduced graphene oxide-coated polyester fabrics

► Graphene-coated fabrics have been obtained by chemical reduction of graphene oxide. ► Conducting fabrics have been obtained applying several graphene coatings. ► Electrochemical impedance spectroscopy showed the conductive behavior of fabrics. ► Scan rate is a key parameter in the characterization by cyclic voltammetry. ► Scanning electrochemical microscopy showed the increase of electroactivity.
