摘要：

A CO2-responsive coating has been developed by adding a thiourea-containing nanocontainer with pH-response release property into an ethyl cellulose coating. The cumulative release of thiourea in the nanocontainer changes with the pH of aqueous solution, which enabled the release rate of thiourea from the nanocontainer in coating to adapt to the change in corrosiveness of 3.5 wt. % NaCl with different dissolved CO2 content. The results of EIS and immersion experiments showed that this environmental responsive nanocontainer can significantly improve the corrosion resistance of the coating in 3.5 wt. % NaCl solution with and without CO2.
