Abstract
The reason for the strong adhesion of polypyrrole (PPy) films to iron and m ild steel surfaces pretreated with dilute nitric acid (HNO3) has been inves tigated by XPS and SERS techniques. It is shown that iron nitride (Fe Xi N) species, arising from the reaction of HNO3 with the metal, an strongly gra fted to the surface. These species could be responsible for the adhesion of PPy films to iron surfaces.
