摘要：

The corrosion inhibition of iron in acid chloride solution offered by a new class of polymer-ortho substituted poly ethoxy aniline, a conducting polymer has been studied. Preparation of polymer by electrochemical and chemical methods has been described. Characterization of this polymer has been done by infrared and UV-vis absorption studies. Its corrosion inhibitive action was examined by the Tafel extrapolation method, linear polarization resistance method, impedance method and direct weight loss method. All these methods confirmed the effectiveness of the inhibitor, indicating also the possibility of monitoring its effectiveness by electrochemical techniques. Double layer capacitance studies indicated strong adsorption of polymer which followed the Temkin isotherm.
