Preparation and corrosion resistance of hydrophobic zeolitic imidazolate framework (ZIF-90) film @Zn-Al alloy in NaCl solution

A review of metal-organic framework protective coatings for light metals

“…easily shielded from the outside world, have abundant electronic energy levels and many energy level transitions applied in chemical sensors and luminescent materials - [ 43] protection of the metals because their hydrophobic surface can effectively block H 2 O and corrosive solutions [61][62][63]. ZIFs [64][65][66][67], MIL-53 [68,69], UiO-66 [70,71] and other hydrophobic MOFs have great application potential in anticorrosion industry due to their good water stability. Zhang et al [64] creatively prepared ZIF-90 coating on the surface of Zn-Al alloy, and the grains were compact and defect-free, which can trap air, so the coating had water repellency and exhibited obvious hydrophobicity (WCA of coating was 112.4°, 71.1°f or bare Zn-Al).…”

“…In recent years, hydrophobic coatings have been widely used in corrosion protection of the metals because their hydrophobic surface can effectively block H 2 O and corrosive solutions [61-63].

Zeolitic imidazolate framework nanoleaves (ZIF-L) enhancement of strength and durability of portland cement composites

“…This observation suggests that the released Zn ions may have partaken a role as sacrificial phase, reducing the acid strength and buffering the attack of acid solution on the cementitious C-S-H and Ca(OH) 2 . Moreover, ZIFs materials have also been previously reported as an efficient anti-corrosion coating due to its hydrophobic properties [67].…”

Fine Tuning the Hydrophobicity of a New Three-Dimensional Cu2+ MOF through Single Crystal Coordinating Ligand Exchange Transformations

“…However, it is well–known that Cu 2+ MOFs including HKUST-1 ,− as well as other MOFs suffer from limited hydrolytic stability. One method to enhance the hydrolytic stability of MOFs is to increase the hydrophobicity of their pore surface and/or external crystal surface. − Such hydrophobic MOFs have attracted significant interest not only because of their stability in water but also due to their diverse potential applications including humid CO 2 capture, − alcohol/water, organic molecules/water and oil/water separations, , removal of pollutants from air or water, , substrate-selective catalysis, and anticorrosion/self-cleaning coatings. , As a result of this interest, several synthetic methods have been reported that lead to MOFs with enhanced hydrophobicity. These synthetic methods include the de novo synthesis of MOFs using ligands containing hydrophobic functional groups ,,,,,− ,, and also postsynthesis modifications (PSM) ,,,− of well–known MOFs.…”
