【摘要】：综述了近几年表面修饰手段在金属-有机骨架(MOF)薄膜制备中的应用研究进展。MOF材料由于具有结构可设计、孔道尺寸可调且可功能化等特点,在气体分离膜领域具有极大的应用价值。制备连续致密MOF膜的关键是解决MOF与基底之间的界面结合问题。表面修饰可改善基底表面的物理化学性质,增强MOF与基底之间的相互作用力。本文从有机分子修饰、无机化合物修饰和MOF晶种修饰三方面入手,介绍修饰手段在MOF薄膜制备中的应用研究进展。其中,着重阐述了不同修饰手段的修饰机理,分析了修饰手段对MOF薄膜的制备及其气体分离性能的影响。研究表明,MOF的种类繁多且成膜过程复杂,有时单一的修饰手段无法制备高质量的MOF薄膜。因此,文中指出根据MOF和基底的性质,选择不同的修饰手段结合使用将是MOF薄膜制备的一个重要发展方向。
[Abstract]:The application of surface modification in the preparation of metal-organic skeleton (MOF) thin films in recent years is reviewed. It has great application value in the field of gas separation membrane. The key to fabricate continuous dense MOF films is to solve the problem of interface bonding between MOF and substrate. Surface modification can improve the physical and chemical properties of the substrate and enhance the interaction between MOF and substrate. In this paper, the application of organic molecular modification, inorganic compound modification and MOF seed modification in the preparation of MOF thin films is introduced. Among them, the modification mechanism of different modification methods and the influence of modification methods on the preparation and gas separation properties of MOF thin films were discussed. The results show that there are many kinds of MOF and the process of film formation is complex, sometimes the single modification method can not be used to prepare high quality MOF films. Therefore, it is pointed out that according to the properties of MOF and substrate, it is an important development direction to choose different modification methods to prepare MOF thin films.
