N2 - 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.
