Recent progress of zeolitic imidazolate frameworks (ZIFs) in superhydrophobic and anticorrosive coatings for metals and their alloys
Journal of Coatings Technology and Research
Metal–organic frameworks (MOFs) have gained interest in recent years for anticorrosion applications owing to their inimitable structures and excellent properties. As a prominent subclass of MOFs, zeolite imidazolate frameworks (ZIFs) exhibited hydrophobicity, corrosion inhibition, and positive water stability, making them frequently appear in the field of metallic anticorrosion. This review presents the establishment and development of a theoretical model for superhydrophobicity, followed by the reported applications of different kinds of ZIFs in the field of metallic anticorrosion with particular emphasis on ZIF-8, which is the most extensively researched structure among ZIFs. In addition, the applications of superhydrophobic coatings in many aspects other than anticorrosion are also summarized. Finally, the existing challenging problems and future development trends of this kind of coating are discussed. It is hoped that this review will contribute to further development in the field of superhydrophobic anticorrosion coatings for metallic materials.
