Abstract In this work, metal organic frameworks (MOFs) are in situ growing on the graphene oxide (GO) sheets to fabricate GO/MOFs nanocontainers for both active and passive corrosion protection. ZIF-8 and UiO-66 are chosen as two classic examples to synthesize GO/MOFs nanocontainers encapsulating benzotriazole (BTA) embedded in polyvinyl butyral (PVB) resin. The composite coatings are successfully utilized in protecting pure copper and archaized bronze, exhibiting both active and passive protecting properties. The passive protection capability is ensured by good barrier performance of GO, and the active prevention property is provided by the pH-stimulated release of embedded inhibitors from the composite nanocontainers.

嵌入具有主动和被动保护特性的 GO/MOFs 纳米容器的涂层

摘要 在这项工作中，金属有机框架 (MOF) 在氧化石墨烯 (GO) 片上原位生长，以制造用于主动和被动腐蚀保护的 GO/MOFs 纳米容器。选择 ZIF-8 和 UiO-66 作为两个经典例子来合成 GO/MOFs 纳米容器，其中包封嵌入聚乙烯醇缩丁醛 (PVB) 树脂中的苯并三唑 (BTA)。复合涂层成功地用于保护纯铜和仿古青铜，具有主动和被动保护特性。GO良好的阻隔性能保证了被动防护能力，而主动防护性能则由嵌入的抑制剂从复合纳米容器中的pH刺激释放提供。
