【摘要】：金属有机骨架材料(MOFs)有着有序的孔道、丰富的结构及功能多样性,在气体分离、储存、催化和传感等方面具有潜在的应用前景,受到科学界的广泛关注。但是MOF晶体具有脆性,容易碎裂,不溶于溶剂,而且不能像高分子一样熔融后热塑成型,常用的压片加工方法得到的样品仍然较易粉化。这些性质极大地制约了MOFs在工业领域的发展和应用。在此,我们向传统的高分子材料学习,把MOFs加工成薄膜、纤维等,并发展了原位聚合法、光引发合成后聚合法、热压组装法、静电纺丝法等一系列方法。从微观结构的设计着手来研究膜的结构与性质的关系,通过不同的方法赋予MOF膜在电化学、分离、检测和安全防护等方面独特的功能和性质,并进一步探索其工业化生产的方法和可能性。
[Abstract]:Organometallic skeleton materials (MOFs) have a wide range of potential applications in gas separation, storage, catalysis and sensing due to their ordered pores and rich structural and functional diversity. However, MOF crystals are brittle, easy to break, insoluble in solvents, and cannot be thermoplastic formed after melting like macromolecules, and the samples obtained by common pressing method are still easy to be powdered. These properties greatly restrict the development and application of MOFs in industrial field. In this paper, we learn from traditional polymer materials and process MOFs into thin films and fibers. We have developed a series of methods, such as in situ polymerization, photoinduced post-synthesis polymerization, hot-press assembly, electrostatic spinning and so on. The relationship between the structure and the properties of the MOF membrane is studied from the microstructural design. The MOF membrane is endowed with unique functions and properties in electrochemistry, separation, detection and safety protection through different methods. And further explore its industrial production methods and possibilities.
