摘要

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.
