Electrochemical Capacitive Properties of Ny/PP/GO Electro-spun Composite Coating on Stainless Steel in Acid Media

Composite materials were manufactured to obtain singular properties be used as in electrochemical driven energy systems. An evaluation was performed on electro-spun nylon 6,6 fibers (Ny), with different concentrations of tetra-para-amino-phenyl porphyrin (PP) and graphene oxide (GO) composite coating over stainless steel (SS), immersed 1M H2SO4 aggressive sulfuric acid solution. Different film coatings behavior obtained compared using impedance spectroscopy (EIS). Also, cyclic voltametry (CV) nylon/PP/GO system at scan rates, covered carbon cloth. For the EIS, lower electro-spinning times present higher impedance, hence some corrosion protection. greater times, larger capacitance values observed. These possibly due thicker or mass transport adsorption-diffusion process through film, respectively. coating, porphyrins, interaction ionic conductivity, reducing promoting proton formation, property which could charge storage
