Innovative layer by layer and continuous growth methods for synthesis of ZIF-8 membrane on porous polymeric support using poly(ether- block -amide) as structure directing agent for gas separation

Synthesis of zeolitic imidazolate framework-8 on polyester fiber for PM2.5 removal

“…It presented remarkable bands at 3455, 3135, 2929, 1635, 1585, 1458, 1425, 1385, 1309, 1146, 995, 760, 694 and 426 cm À1 for ZIF-8 sample. These FT-IR bands were consistent with those previously reported by Cravillon et al, Ordonez et al and Jomekian et al [35][36][37] The band at 3455 cm À1 might be attributed to the N-H stretching vibration of the residual Hmim and the O-H stretching vibration of water from KBr deliquescence. The peaks at 3135 and 2929 cm À1 were associated with the aromatic and aliphatic C-H asymmetric stretching vibrations, respectively.…”

Influence of the 2-methylimidazole/zinc nitrate hexahydrate molar ratio on the synthesis of zeolitic imidazolate framework-8 crystals at room temperature

“…40 and Jomekian et al . 41 . The band at 3455 cm −1 might be attributed to the N–H stretching vibration of the residual Hmim and the O–H stretching vibration of water from KBr deliquescence.…”

A mini‐review and recent outlooks on the synthesis and applications of zeolite imidazolate framework‐8 (ZIF‐8) membranes on polymeric substrate

“…2(D). 11,15 When using this technique, the polymeric substrate was first immersed in a precursor solution containing the metal ions. It was then subsequently immersed in a ligand precursor solution, followed by washing and drying.…”

“…The simplest strategy to grow ZIF‐8 membrane based on this method is to directly immerse the polymeric substrate into MOF precursor solutions. Various polymers have been investigated using this approach, such as polysulfone (PSF), polyphenylsulfone (PPSU) and polyimide (PI) . In this approach, controlling the synthesis condition is important since it will affect both the particle size of the ZIF‐8 and the final membrane structure .…”
