Abstract: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
   MnO_2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 MnO_2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 MnO_2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。
