Abstract
Corrosion behavior of stainless steel was investigated by using highly processable polyanilinedodecylbenzenesulfonic acid (PANI-DBSA) salt. An Electroactivity/redox property of the polymer was investigated by cyclic voltammetry. Conducting salt form of PANI-DBSA was studied by UV-Vis spectroscopy. A solution of PANI-DBSA was drop coated on stainless steel electrode. Corrosion performances of PANI-DBSA coated and un-coated electrodes were investigated in 3% sodium chloride (NaCl) by means of DC corrosion (E Tafel) technique. The results show that PANI coating increased the corrosion resistance of stainless steel in an aggressive sodium chloride medium.
