Abstract
Poly(methacrylic acid)/silver nanoparticles (PMAA/AgNPs) composite was prepared in-situ and characterized by UV-vis spectroscopy, FTIR, TEM, XRD, and EDS. The anticorrosion performance of the composite was investigated by gravimetric, electrochemical, SEM, EDS, and water contact angle measurements. Results obtained show that PMAA/AgNPs act as corrosion inhibitor for mild steel in 0.5 M H2SO4 solution. Inhibition efficiency increased with increase in concentration and temperature. PMAA/AgNPs composite behaved as a mixed-type corrosion inhibitor and adsorption onto the metal surface followed Temkin adsorption isotherm model. Results from all the surface analyses confirm the formation of PMAA/AgNPs protective film on the mild steel surface.
