Titanium Silicon Oxide Nanoflower Coated Polyaniline Nanocomposite for Enhancement of Corrosion Protection Performance on Mild Steel

摘要

In this study PANI/titanium silicon oxide (PTS) nanoflower coated nanofiber has been synthesized by chemical oxidation method. PANI nanocomposite has been applied as a corrosion protective material which helps in improving the corrosion resistance of various metal oxides such as titanium silicon dioxide which has been renowned as most promising electrode material for corrosion inhibition. The possible interactions between PANI and titanium silicon oxide and morphological characteristics of the synthesized nanocomposite were investigated by FTIR, XRD, TEM and SEM. The anticorrosion performance of different PANI/titanium silicon oxide (PTS) nanocomposites coatings were investigated in 0.5 M HNO3 medium by the potentiodynamic technique and electrochemical impedance spectroscopy (EIS) on mild steel. The most pronounced improvement in anticorrosion property of PANI was obtained by using 15% PTS composition of synthesized nanocomposite. The performance of this nanocomposite as an anticorrosive material has been investigated through EIS on mild steel.
