摘　　要：本研究采用辐射诱导法在柔性聚合物基材上制备了连续金属-有机框架Zn(bdc)(dabco)_(0.5)膜,通过X射线衍射、傅里叶红外光谱和扫描电子显微镜等对其形貌和结构进行了表征,并通过BET比表面积测定、密度泛函理论孔径分析以及单组分吸附等温线的测定来研究了连续金属-有机框架Zn(bdc)(dabco)_(0.5)膜的轻烃吸附性能。研究结果表明,相比甲烷,Zn(bdc)(dabco)_(0.5)膜对乙烷和丙烷具有较高的吸附。且Zn(bdc)(dabco)_(0.5)膜具有更高的乙烷/甲烷选择性(常压下达到11)和丙烷/甲烷选择性(常压下达到10),这一工作体现了MOF膜在分离领域中独特的优势。This article describes the preparation of continuous metal-organic framework(MOF)Zn(bdc)(dabco)_(0.5) membranes on flexible polymer substrates using a radiation-induced method.The morphologies and structures of the membranes were investigated using X-ray diffraction,Fourier-transform infrared spectroscopy,and scanning electron microscopy.Their light hydrocarbon-adsorption properties were characterized using Brunauer-Emmett-Teller specific surface area measurements,density functional theory pore-size analysis,and singlecomponent adsorption isotherms.The results indicated that the Zn(bdc)(dabco)_(0.5) membranes exhibited higher adsorption for ethane and propane than for methane.Moreover,the Zn(bdc)(dabco)_(0.5) membranes showed enhanced ethane/methane selectivity(reaching 11 at atmospheric pressure)and propane/methane selectivity(reaching 10 at atmospheric pressure).This study demonstrates the unique advantages of MOF membranes in the field of separation.
