Corrosion protection of mild steel (MS) substrate is critical to prolonging the life of service equipment in refineries and chemical industries. In petroleum refineries, drilling and acidizing pipe work with vast amounts of 15% HCl that induce corrosion of MS pipelines. Here, a novel pentadecyl phenol (originated from cashew nut shell liquid)-functionalized conjugated polypyrrole (MPY) was synthesized and demonstrated for MS corrosion inhibition at a 15% HCl environment. Pentadecyl units provide hydrophobicity and form interdigitating layer structures to cover the metal substrate, which leads to better corrosion mitigation. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) studies reveal the superior corrosion inhibition performance of MPY on MS under 15% HCl conditions. The corrosion protection efficiency was determined to be 67.93% over MS substrate in the presence of MPY from PDP studies compared with pure MS. [ABSTRACT FROM AUTHOR] |
