The fabrication and corrosion resistance of benzotriazole-loaded raspberry-like hollow polymeric microspheres
Surface and Coatings Technology(2014)
Abstract
This work presents a synthesis of submicron-sized raspberry-like hollow microspheres loaded with corrosion inhibitor (1H-benzotriazole (BTA)) through a multi-stage emulsion polymerization. The combination of hierarchical raspberry-like surface structure and loading of BTA makes the prepared microspheres have good corrosion resistance. When BTA-loaded raspberry-like hollow microspheres are embedded in a water-borne polyurethane film, the obtained composite film can protect the copper from corrosion both in acidic and alkaline corrosive solutions.
