使用外观观察、开路电位以及线性极化电阻等方法研究了聚苯胺对碳钢腐蚀的阻化作用 .尽管质子化的聚苯胺具有导电性 ,使线性极化电阻低于相应的对照样品 ,但质子化的聚苯胺在碳钢和电解液间形成的阻档层的作用 ,使质子化的聚苯胺也显示出一些阻止腐蚀作用 .从线性极化电阻以及外观观察的结果可以看出 ,0 %质子化的聚苯胺表现出好的阻化作用 ,其主要作用是腐蚀过程从均匀腐蚀变化成局部点蚀 .这可能是该化合物被溶解在水溶液中 ,提供一种完全的阻化作用 ,并以某种方式在与钢接触的表面保持该物质具有较高的浓度
The effect of polyaniline on the corrosion resistance of carbon steel was studied by the methods of appearance observation, open circuit potential and linear polarization resistance.Although the protonated polyaniline has conductivity and the linear polarization resistance is lower than that of the corresponding control sample, the proton The effect of the polyaniline on the barrier layer formed between the carbon steel and the electrolyte makes the protonated polyaniline also show some corrosion inhibition.As can be seen from the results of the linear polarization resistance and the appearance observation, 0% proton The polyaniline shows a good resistance, its main function is to change the corrosion process from uniform corrosion to localized pitting, which may be that the compound is dissolved in aqueous solution to provide a complete resistance to oxidation. The way to maintain contact with the steel to keep the material has a higher concentration
