In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method and their morphological and spectral properties were investigated using XRD, SEM, FTIR, and Raman spectroscopy. XRD studies of powder samples revealed the presence of an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which were prepared through two different chemical routes, showed no additional phases. A detailed analysis of the FTIR and micro-Raman spectra of the composite samples revealed the formation of stable ZIF structures inside the macropores of the MCG substrate. The hydrophilic nature of the MCG substrate and its interaction with the ZIF structure resulted in the formation of stable ZIF-MCG composites. We believe that these composite materials may find a wide range of important applications in the field of sensors, molecular sieving.
在本研究中，采用水热法制备了包含沸石咪唑酯骨架（ZIF）结构和微通道玻璃（MCG）板的新型复合材料，并利用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和拉曼光谱对其形态和光谱性质进行了研究。粉末样品的XRD研究表明，ZIF-8样品存在额外相，而通过两种不同化学路线制备的ZIF-67样品未显示额外相。对复合样品的FTIR和显微拉曼光谱进行详细分析后发现，在MCG基底的大孔内形成了稳定的ZIF结构。MCG基底的亲水性及其与ZIF结构的相互作用导致形成了稳定的ZIF-MCG复合材料。我们认为，这些复合材料可能在传感器、分子筛等领域找到广泛的重要应用。
