“…This large surface area makes these materials good substrates on which to deposit other materials for different Page 3 of 38 A c c e p t e d M a n u s c r i p t 3 applications. For example fabrics have been coated with conducting polymers to produce conductive fabrics [11,12], with silver or TiO 2 nanoparticles to produce antibacterial fabrics [13], with single walled nanotubes and MnO 2 [14] or graphene and MnO 2 [15] to produce super-capacitors, etc.…”

Reduced graphene oxide (RGO) coated fabrics were obtained by chemical reduction of GO on polyester (PES) fabrics. Conducting fabrics that have different applications were obtained by applying several layers of RGO. Electrochemical techniques not traditionally used for the characterization of these materials were used to test their electrical and electrochemical properties. Electrochemical impedance spectroscopy was used to measure the electrical properties. The resistance of the original PES was more than 10 11 Ω·cm 2 , but when coated with three RGO layers, the resistance decreased to 23.15 Ω·cm 2 . Phase angles changed from 90º for PES and PES-GO (capacitative behavior) to 0º for all the RGO coated samples (resistive behavior). Electro-activity was measured by cyclic voltammetry (CV) and scanning electrochemical microscopy. An increase in electro-activity was observed when the inactive GO was reduced to RGO.With CV an increase of electro-activity was observed with an increasing number of RGO layers. The contact between the different RGO sheets is responsible for the electric conduction in the fabrics. The techniques used showed that with only one RGO 1 ISE memberPage 2 of 38 A c c e p t e d M a n u s c r i p t 2 coating, the contact between the RGO sheets is not good and more coatings were needed to assure good electrical and electrochemical properties.

“…Different methods have been employed to provide the fabrics with electrical conductivity. For example the use of metallic fibers inserted in the fabric, chemical metallization of fibers [5], the extrusion of fibers with conductive particles such as carbon derivatives [6] or the synthesis of conducting polymer films on the fabrics [7][8][9].…”

The phase angle also changed from 90º for PES-GO (capacitative behavior) to 0º for RGO coated fabrics (resistive behavior). In general an increase in the number of RGO layers produced an increase of the conductivity of the fabrics. EIS measurements in metal/sample/electrolyte configuration showed better electrocatalytic properties and faster diffusion rate for RGO specimens. Scanning electrochemical microscopy was employed to test the electroactivity of the different fabrics obtained.The sample coated with GO was not conductive since negative feedback was obtained.When GO was reduced to RGO the sample behaved like a conducting material since positive feedback was obtained. Approach curves indicated that the redox mediator had influence on the electrochemical response. The Fe(CN) 6 3-/4-redox mediator produced a higher electrochemical response than Ru(NH 3 ) 6 3+/2+ one.
