通过模板法制备了二氧化锰微米容器，利用脱溶剂法实现了微米容器对苯并三氮唑(BTA)的封装。通过扫描电子显微镜和X射线衍射仪表征了微米容器的表面形貌及晶体结构，使用红外光谱确定了微米容器对BTA缓蚀剂的负载，利用紫外可见分光光度计、交流阻抗谱、动电位极化曲线等测试手段分析了携载BTA缓蚀剂的MnO2微米容器在模拟海水中BTA的释放速率及缓蚀性能。结果表明，脱溶剂法可有效地实现MnO2微米容器对BTA缓蚀剂的封装，封装量为3.9%，而且携载BTA缓蚀剂的MnO2微米容器在3.5%NaCl溶液中能有效地释放BTA，实现了对铜基体的腐蚀防护。

The MnO2 micro-containers were prepared by template method, and then used to encapsulate benzotriazole (BTA), a corrosion inhibitor, through desolvation process. The surface morphology and crystal structure of the micro-containers were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The loading of BTA in MnO2 micro-containers was confirmed by Fourier-transform infrared spectroscopy (FT-IR), and the releasing rate of BTA from the micro-containers in simulated seawater was analyzed by ultraviolet-visible spectrophotometry (UV), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization curve measurement. The results indicated that BTA can be effectively encapsulated by MnO2 micro-container by desolvation process with a loading capacity up to 3.9%, and releases effectively from MnO2 micro-container in 3.5%NaCl solution, achieving the corrosion protection for copper substrate.
