Synthesis Of Poly P-Aminophenol/Tio2 Composite In The Presence Of Anionic Surfactants And The Investigation Of Anticorrosion Properties

“In situ” polymerization was carried out in the presence of TiO2 to synthesize polypara aminophenol/ TiO2 (PpAP/TiO2) composite using anionic surfactants DBSA and SDS at 0˚C and characterized by FTIR, UV–VIS-NIR spectroscopy, XRD and TGA. The corrosion protection performances of composites on Mildsteel in 1M HCl solution were evaluated using Potentiodynamic polarization and Electrochemical impedance spectroscopy measurements. These measurements reveal that the inhibition efficiency increased by increasing their concentration. Polarization studies reveal that composites act as a mixed type corrosion inhibitor. It was found that this inhibitor acts through adsorption on the metal surface and obeys Langmuir adsorption isotherm.
