Abstract
Poly(Sodium-2-Acrylamido-2-methylpropane) Sulfonate, PNa-AMPS nanocomposite consisting of a nanocrystalline titania matrix was prepared by suspension of the titania particles followed by crosslinking radical polymerization of Na-AMPS monomer. The chemical structure of the prepared nanogel was evaluated by FTIR. The crystallinity, morphology and particle size distribution were characterized by XRD patterns, TEM and DLS analyses. The high corrosion inhibition effectiveness of TiO2 nanoparticles in chloride containing environment is reported using electrochemical techniques. All measurements showed that TiO2 nanoparticles had excellent corrosion protection for the corrosion of steel in acidic chloride solution and the protection efficiency is strongly dependent upon inhibitor concentration.. Polarization data reveal that TiO2 nanoparticles act as a mixed-type inhibitor.
