A novel multi-corrosion inhibitors-halloysite nanocomposite was successfully synthesized by stepwise loading 2-Mercaptobenzothiazole (MBT) and benzotriazole (BTA) into halloysite nanotubes (HNTs), then the insoluble Cu-BTA complex was introduced at the end of HNTs (defined as “Cu-BTA-MBT-HNTs”) to control the release rate of MBT and BTA. The prepared Cu-BTA-MBT-HNTs can not only reduce the release rate of MBT and BTA for achieving the sustained release effect, but also an acid-response complex corrosion inhibitors. Moreover, the Q235 steel in 3.5% NaCl + Cu-BTA-MBT-HNTs solution owns high inhibition efficiency. Therefore, the Cu-BTA-MBT-HNTs can be a very promising multi-corrosion inhibitors-halloysite nanocomposite.

通过将2-巯基苯并噻唑（MBT）和苯并三唑（BTA）逐步加载到埃洛石纳米管（HNTs）中，成功合成了一种新型的多腐蚀抑制剂-卤化钾纳米复合物，然后在HNTs的末端引入了不溶性的Cu-BTA络合物（定义为“ Cu-BTA-MBT-HNTs”）来控制MBT和BTA的释放速率。所制备的Cu-BTA-MBT-HNTs不仅可以降低MBT和BTA的释放速率以达到持续释放的效果，而且还可以作为酸响应复合缓蚀剂。此外，Q235钢在3.5％NaCl + Cu-BTA-MBT-HNTs溶液中具有较高的抑制效率。因此，Cu-BTA-MBT-HNTs可能是一种非常有前途的多腐蚀抑制剂-硅藻土纳米复合材料。
