An ideal microcapsule effectively preserves an active substance and can rapidly release it to elicit a self-healing anticorrosion effect. However, the development of highly efficient microcapsules remains challenge. In this study, polymer/metal-organic framework hybrid with dynamic properties were constructed as coatings. The shell consisted flexible polydopamine hard crystalline zeolitic imidazolate framework-8 (ZIF-8) layer. corrosion inhibitor 8-hydroxyquinoline (8-HQ) was trapped in remained unreleased because ZIF-8 layer acted molecular sieve. When coating surrounded by acidic environment, nanocrystals dissociated, followed 8-HQ. A dense protective formed on steel surface suppress extensive propagation. |
