Fabrication of dual self-healing silane nanocomposite for efficient corrosion protection of aluminum alloy
Source abstract
Abstract
1,5-naphthalenediol (ND) inhibitor loaded hollow CeO 2 nanoparticles were incorporated into superhydrophobic silane coating on aluminum alloy for corrosion protection. The hollow CeO 2 nano-carrier exhibited a large loading amount of 23.5 wt%. The corrosion protection and self-healing performance was investigated by using electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) in 3.5 wt% NaCl solution. EIS result indicated that the constructed silane/CeO 2 @ND composite coating significantly enhanced the corrosion resistance and the inhibition efficiency was 97.9%. Meanwhile, the localized corrosion was remarkably suppressed from EN measurements. Moreover, the silane/CeO 2 @ND composite coating exhibited an excellent chemical and mechanical stability and self-healing ability due to the synergistic effect of incorporated inhibitive CeO 2 nanoparticles and the loaded effective ND inhibitor.
