AbstractIn this work, a new type of cerium oxide particles with a graded mesoporous structure (Hierarchically mesomesoporous cerium oxide, HMCe) was prepared as both inhibitor and carrier for loading 2-MBI (2-mercaptobenzimidazole) inhibitor, which was encapsulated by Eudragit E100 (EE100, a kind of amino methacrylate copolymer) to construct smart containers with pH controlled-release properties. The smart containers were added to a water-borne epoxy coating to develop active anti-corrosion coating on mild steel. The corrosion inhibition effect of 2-MBI and mesopomus cerium oxide particles was evaluated. Furthermore, the release of 2-MBI from the smart containers in response to acidic corrosion solution was also investigated using UV-vis spectroscopy. Electrochemical impedance spectroscopy (EIS) and salt spray tests were employed to evaluate the barrier properties and the active anti-corrosion performance of the coatings. The results showed that coating with newly designed smart containers has better anti-corrosion performance than coating with cerium oxide particles or 2-MBI alone. This work provides a new way to fabricate containers and actively protective coatings.
