Abstract
This work is aimed at developing and investigating silane based organic–inorganic hybrid polyacrylamide nanocomposite possessing unique properties, which can be used to improve the corrosion inhibition of steel subjected to corrosion. The nanocomposite was prepared using dispersion radical polymerization technique. Silica/polyacrylamide nanocomposite with various concentrations have been tested as potential inhibitor against corrosion of steel in 1 M HCl solution using electrochemical techniques. The nanocomposite behave as mixed type inhibitor and forms an inhibitive layer on the metal surface The inhibition efficiency increased with increase in concentration of silica/polyacrylamide nanocomposite. It was found that the silica/polyacrylamide nanocomposite. inhibited the acid induced corrosion of steel better than experienced by silica alone.
