Abstract
P(ANI-co-PY) and P(ANI-co-PY)-MoO42? copolymer coatings with different molar ratios of aniline (ANI) and pyrrole (PY) monomers are electrosynthesized on the surface of a 304 stainless steel (304SS) in 1-butylsulfonic acid-3-methylimidazolium hydrogensulfate (BAMH) ionic liquid solution using cyclic voltammetry (CV) technique. P(ANI-co-PY) and P(ANI-co-PY)-MoO42? copolymer coatings possess better surface compactness and thermostability than the pure PANI and PPY coatings. 1H NMR studies and UV
