Abstract
A simple method was applied to prepare coated silver nanoparticles with polymerizable surfactants. In this respect, Noigen R-N10 was modified by esterification with maleic anhydride. The produced surfactant was used as dispersing agent for silver nanoparticles, which prepared from AgNO3. The size and the morphology of the nanoparticles have been examined by conventional and high-resolution transmission electron microscopy. The prepared silver nanoparticles has size ranging from 25 to 80 nm, while the diameters ranging from 2 to 18 nm The prepared silver nanoparticles have been employed as corrosion inhibitor for carbon steel in 1M HCl solution using electrochemical impedance spectroscopy (EIS) technique. EIS data indicated that silver nanoparticles reduced drastically the corrosion rate of carbon steel and exhibit good performance as well as barrier property against the corrosion in HCl solution.
