摘要：

This work presents a simple and facile one-step encapsulation method to fabricate benzotriazole@zinc oxide (BTA@ZnO) microcapsules. The morphology, size and chemical composition of as-prepared microcapsules were characterized by electron microscopy, Fourier-transform infrared spectroscopy and X-ray diffraction. Meanwhile, the encapsulation and releasing behaviour of BTA in BTA@ZnO microcapsules were investigated. Results showed that BTA had higher encapsulation efficiency and could be slowly released over a time period of 56 h. In addition, the electrochemical impedance spectroscopy and water uptake experiments demonstrated improved performance in corrosion and water resistance of waterborne polyacrylate coating through introducing BTA@ZnO microcapsules.
