Poly(o-bromophenol-co-N-methylaniline) [poly(OBP-co-NMA)] was electropolymerized in an acidic medium at 30°C under inert atmosphere. The formed polymer was characterized using IR spectroscopy, XRD, SEM and TGA analysis. The efficiency of the deposited polymer as a corrosion protection coating on a mild steel electrode in an acidic medium was investigated. Corrosion and impedance measurements reveal that the prepared polymer has excellent passivation properties. The free energy of adsorption of the prepared polymer on the electrode surface was in the range of ≈ − 19.5 kJ mol⁻¹, which reveals a physical adsorption of the inhibitor molecules on the metallic surface.

聚（邻溴苯酚-co- N-甲基苯胺）[聚（OBP-co-NMA）]在酸性介质中在惰性气氛下于30℃电聚合。使用IR光谱，XRD，SEM和TGA分析对形成的聚合物进行表征。研究了在酸性介质中在高碳钢电极上沉积的聚合物作为防腐涂层的效率。腐蚀和阻抗测量表明，所制备的聚合物具有优异的钝化性能。制备的聚合物在电极表面上的吸附自由能在≈-19.5kJmol ^-1的范围内，这表明抑制剂分子在金属表面上的物理吸附。
