Abstract
An intelligent corrosion inhibitor for enhanced corrosion protection in acidic environment was developed based on benzotriazole (BTA) and photo-crosslinked poly(2-dimethylaminoethyl methacrylate) [poly(DMAEMA)] hydrogel carrier. By varying the ratio of monomer to crosslinker and overall monomer and crosslinker concentrations, an optimized composition that showed an extremely low swelling ratio of ~3.8 at pH=8 and a high swelling ratio of ~32 at pH=2 was selected as the intelligent carrier to demonstrate the pH-dependent release of BTA. Polarization curves and electrochemical impedance spectroscopy both revealed that the intelligent corrosion inhibitor had the unique advantage of long-term protection over copper corrosion because of the highly sustained BTA supply.
