摘要: Abstract Polypyrrole coatings with varying surface morphology have been formed on a stainless steel working electrode using benzene sulfonic acid sodium salt as the electrolyte. The of varied current density. amount polypyrrole during electropolymerization increased density and monomer concentration, but was unaffected by electrolyte concentration. potential pyrrole efficiency remained relatively unchanged at 99–105%. rate onto slightly decreased
