金屬管道、鍋爐酸洗過程中，金屬腐蝕不可避免，緩蝕劑是延緩金屬腐蝕最有效、最經(jīng)濟(jì)的材料。苯胺低聚物具有可逆氧化還原特性，作為一種新型防腐蝕材料受到人們廣泛關(guān)注。合成了一種水溶性良好的H3PO4摻雜聚苯胺納米粒子緩蝕劑，采用動電位極化曲線和交流阻抗譜技術(shù)研究該緩蝕劑在1 mol/L HCl鹽酸洗液中對碳鋼的緩蝕性能和緩蝕機(jī)理，并結(jié)合掃描電鏡和電子能譜分析碳鋼腐蝕形貌和腐蝕產(chǎn)物成分。結(jié)果表明：H3PO4摻雜聚苯胺納米粒子在碳鋼表面吸附成膜，抑制氯離子對碳鋼侵蝕，屬于陽極型緩蝕劑。當(dāng)緩蝕劑濃度為05g/L時(shí)，120min后的緩蝕效率高達(dá)949%。
- Abstract:

During the acid pickling process of metal pipeline and boiler, the corrosion of metal is inevitable. Inhibitor is the most effective and economical way to decrease the corrosion rate of metal．Aniline oligomer possesses reversible redox performance，which enables them to be the new anticorrosion agents，and their anticorrosion performance has attracted intense attentions. Aniline oligomer is an important metal corrosion inhibitor. A water soluble inhibitor, H3PO4 doped PANi nanoparticle, was synthesized by dispersion polymerization technology. The corrosion performance and corrosion mechanism of PANi nanoparticle on carbon steel in 1 mol/L HCl were investigated by polarization curves and electrochemical impendence spectroscopy (EIS). The corrosion product morphology and corrosion product components of carbon steel were also analyzed by electron scanning microscope(SEM) and energy dispersive spectroscopy (EDS). Results indicated that H3PO4 doped PANi nanoparticle is an anodic corrosion inhibitor which formes a compact film on carbon steel surface and then inhibits the erosion of Cl-. When the concentration of inhibitor is 05 g/L, its inhibition efficiency reaches 949% after 120 min.
