摘要/Abstract

摘要：

高分子气体分离膜具有价格低和易加工等优点，但存在气体分离性能难以满足工业要求，以及耐老化性能和结构稳定性差等问题。炭分子筛膜不仅具有高力学性能，高耐热、耐化学腐蚀性能，而且存在适合气体传递的路径、对气体分子亲和性好的杂原子结构，以及分子辨识能力强的孔尺寸，表现出优异的气体分离性能，因而受到广泛的关注，被认为是最具应用前景的气体分离膜。6FDA型聚酰亚胺不仅具有较大的刚性和受限制的构象，且自由体积较大、分子结构可调、成孔性好和残炭量高，制备的炭分子筛膜的气体分离性能优于其他前体，受到学术界和工业部门的青睐。本文主要介绍了炭分子筛膜前体的结构设计原理，在热解过程中的炭化机理和微观结构的控制，炭结构对气体分离性能的影响，气体在膜中的传递机理，以及由6FDA型聚酰亚胺制备的炭分子筛膜在气体分离中的应用。结合科研实际，提出了6FDA型聚酰亚胺炭分子筛膜结构设计和制备的想法，为未来炭分子筛膜在气体分离中应用提供新的思路。

Abstract:

Polymer gas separation membranes have the advantages of low price and easy processing, but there are problems such as gas separation performance is difficult to meet the industrial requirements, and the aging resistance and structural stability are poor. Carbon molecular sieve (CMS) membranes have high mechanical properties, high heat and chemical corrosion resistance, suitable gas transport paths, heteroatomic structure with good affinity for gas molecules and pore size structure with strong molecular discrimination, exhibiting excellent gas separation performance, thus receiving wide attention and being considered as a promising gas separation membrane. The 6FDA-based polyimide not only has larger rigidity and restricted conformation, but also has larger free volume, adjustable molecular structure, good pore formation and high carbon residue, and the gas separation performance of as-prepared CMS membranes are better than that prepared by other precursors, which is favored by the academic and industrial sectors. This paper introduces the structural design principle of CMS membranes precursors, carbonization mechanism during the pyrolysis processes and the control of microstructure, the influence of carbon structure on gas separation performance, the gas transport mechanism in the membrane, and the application of CMS membranes prepared by 6FDA-based polyimide in gas separation. In combination with our own scientific research practice, the strategy of the structure design and preparation of CMS membranes prepared by 6FDA-based polyimide is proposed to provide new ideas for the future application of CMS membranes in gas separation.
