摘要: Abstract Poly( N -methylpyrrole) coatings have been electrodeposited on steel substrates from aqueous oxalate solutions. The formation process of the was found to be different between acidic and basic mediums. In an medium, reactions were characterized by two stages: passive interphase electropolymerization -methylpyrrole. composition formed poly( examined infrared spectroscopy (IR) X-ray photoelectron (XPS). Our results show that in medium is composed iron(II) dihydrate. occurred after passivation completed. Interaction -methyl pyrrole) shown broadening –CO absorption peak.
