In Situ Synthesis of ZIF-8 Loaded with 8-hydroxyquinoline Composite via a Host-Guest Nanoconfinement Strategy for High-Performance Corrosion Protection

Abstract

A strategy based on in situ host-guest nanoconfinement was used to assist the synthesis of a ZIF-8 host loaded with a corrosion inhibitor 8-hydroxyquinoline (8-HQ) guest by a facile one-step process at room temperature. Results showed that a Zn-(bis-8-hydroxyquinoline) guest encapsulated ZIF-8 host composite (Q@ZIF-8) was formed. The Q@ZIF-8 proves to have an inhibition efficiency of over 91% to protect the aluminum alloy substrate against corrosion in the corrosive solution after 2 days. Additionally, the pH-responsive Q@ZIF-8 can release 8-HQ species in form of hydroxyquinoline zinc complex and improves the corrosion resistance of the epoxy coating.
