聚合物/无机纳米粒子复合膜在气体分离中的研究进展

由于聚合物膜具有可高度设计、机械性能好、易于加工 等优点，是理想的气体分离材料。然而，聚合物膜在气体选择性和渗透性方面存在平衡限制，在聚合物中引入纳米粒子，是提高气体分离性能的一种有效手段。本文基于聚合物/无机纳米粒子复合膜在气体分离领域的研究现状，重点阐述了零维纳米粒子（二氧化硅、二氧化钛）、一维纳米粒子（碳纳米管）、二维纳米粒子（氧化石墨烯、二维过渡金属氧化物）、三维纳米粒子（金属有机框架、沸石）对气体分离性能的影响，并展望了聚合物复合分离膜的发展趋势，为未来高效分离膜的研发提供了参考。

Research Progress of Polymer/Inorganic Nanoparticle Composite Film for Gas Separation

Polymer membranes are considered to be ideal materials for gas separation technology due to the strong designability, excellent mechanical properties and simple processing. However, polymer membranes often suffer a trade-off between permeability and selectivity. To overcome this limitation, incorporation of inorganic nanoparticle into membranes is one of effective ways to improve the gas separation performance of membranes. According to the research status of polymer/inorganic nanoparticle composite film in the field of gas separation, zero-dimensional nanoparticles (silicon dioxide and titanium dioxide), one-dimensional nanoparticles (carbon nanotubes), two-dimensional nanoparticles (graphene oxide and two-dimensional transition metal oxides), three-dimensional nanomaterials (metal-organic frameworks and molecular sieves) are described emphatically in this article. Finally, the development prospect of polymer/inorganic nanoparticle composite membranes in gas separation is forecasted, which provides a reference for the research and development of high-efficiency separation membranes in the future.
