摘要：

Poly(styrenesulphonic acid)-doped polyaniline has been synthesised and the influence of this polymeric compound on the inhibition of corrosion of mild steel in 1 M HCl has been investigated using weight loss measurements, galvanostatic polarisation studies, electropermeation studies and a.c. impedance measurements. The polymer acts predominantly as an anodic inhibitor. Hydrogen permeation studies and a.c. impedance measurements clearly indicate a very effective performance of the compound as a corrosion inhibitor. The adsorption of the compound on the mild steel surface obeys Temkin's adsorption isotherm.
