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.

在石英晶体传感器上制备用于吸附CO _2的均质咪唑沸石骨架薄涂层

已经通过浸涂法在玻璃和石英晶体微天平（QCM）基板上制作了四个沸石-咪唑酸盐骨架（ZIF-8，ZIF-67，ZIF-7和ZIF-93）的薄膜。对于ZIF-8，ZIF-67，ZIF-7和ZIF-93，获得的均相涂层的晶体尺寸分别为65±20、285±96、61±20和72±21 nm。通过XRD，TGA，SEM，FTIR，接触角测量和N ₂吸附表征ZIF和涂层后，将涂层暴露于二氯甲烷蒸气中进行活化。然后使用QCM设备研究涂层对CO _2的吸附。
