Polyaniline Nanoparticles Prepared by Micro-Emulsion Polymerization for Corrosion Inhibition of Carbon Steel in 1M HCl
Abstract: Polyaniline nanoparticles were prepared using oxidation polymerization in micro-emulsion system. Sodium dodecyl sulphate was used as a surfactant which dissolved in hydrochloric acid giving the micellar solution. Potassium persulphate was used as an oxidant. The produced particles were spherical in shape with an average diameter of 15 nm as detected from the transmittance electron microscope images. Polyaniline nanoparticles were investigated as corrosion inhibitors using electrochemical measurements. It has been found that nanopolyaniline is an efficient inhibitor, since the maximum efficiency of 94 % has been observed at a concentration of 500 ppm.
Keywords: Polyaniline, nanoparticles, electrochemical measurements, corrosion
