Surface morphology and corrosion inhibitors of acrylate/carbon nanotubes nanocomposites coated on mild steel

Abstract

The conducting polymer nanocomposites of acrylate/carbon nanotubes were coated on mild steel to investigate corrosion performance for coating application. Corrosion protection performance of acrylate/carbon nanotubes nanocomposites thin film coating was determined by immersed in 3.5 % sodium chloride. Carbon nanotubes with various weight percentages (0.2 %, 0.4 %, 0.6 %, 0.8 % and 1.0 %) blending into acrylate and deposited on mild steel by using sol-gel method. Atomic force microscope (AFM) and electrochemical impedance spectroscopy (EIS) was used to determine the surface morphology and corrosion protection of mild steel immersed in 3.5 % of sodium chloride, (NaCl) that coated by acrylate/carbon nanotubes nanocomposites thin film as an inhibitors for corrosion protection.

Research on Adhesion and Properties of Composite Coating on Aluminized Carbon Steel

“…For example, Zhang et al found that the increase of Al 2 O 3 content in the composite coating can significantly improve the hardness and wear resistance of the coating by conducting research. In addition, the study shows that different preparation and process conditions significantly affect the properties of the composite coating [3].…”
