Abstract

Thin films of four zeolitic-imidazolate frameworks (ZIF-8, ZIF-67, ZIF-7, and ZIF-93) have been fabricated by a dip-coating method on glass and quartz crystal microbalance (QCM) substrates. Homogeneous coatings with sizes of crystals of 65 ± 20, 285 ± 96, 61 ± 20 and 72 ± 21 nm for ZIF-8, ZIF-67, ZIF-7, and ZIF-93, respectively, were obtained. Upon characterization of the ZIFs and coatings by XRD, TGA, SEM, FTIR, contact angle measurement and N₂ adsorption, the coatings were exposed to vapors of dichloromethane for activation. The CO₂ adsorption of the coatings was then studied using a QCM device.
