Abstract

Metal corrosion has caused great damage to resource economy, and corrosion protection is particularly important. In this paper, GMZT(GO-MBI-ZIF-67-TEOS) nanomaterial was synthesized to prepare the coating. GMZT nanomaterials were mixed with epoxy resin (EP) electrophoretic coating, and the coating was prepared by electrophoretic deposition (EPD) method. Electrochemical impedance spectroscopy (EIS) test results show that the impedance modulus of GMZT/EP is 3 orders of magnitude higher than that of EP after 35 days, which enhances the anticorrosion property of the base film, and the GMZT/EP coating has excellent self-healing property. This is due to the release of the ZIF-67 dissociation ligand and the addition of inhibitors, which form a dense protective film on the metal surface. As a result, the barrier/active anticorrosion properties of epoxy coatings are improved, resulting in superior and long-lasting anticorrosion.

ph刺激响应型ZIF-67纳米容器掺杂智能防腐环氧涂料的电泳沉积

金属腐蚀对资源经济造成了巨大的破坏，腐蚀防护显得尤为重要。本文合成了GMZT（GO-MBI-ZIF-67-TEOS）纳米材料来制备该涂层。将GMZT纳米材料与环氧树脂（EP）电泳涂层混合，采用电泳沉积（EPD）法制备涂层。电化学阻抗谱（EIS）测试结果表明，35天后GMZT/EP的阻抗模量比EP高3个数量级，增强了基膜的防腐性能，且GMZT/EP涂层具有优异的自愈性能。这是由于ZIF-67解离配体的释放和抑制剂的加入，在金属表面形成了致密的保护膜。因此，环氧涂料的屏障/活性防腐性能得到了改善，从而实现了卓越和持久的防腐。
