材料研究是使合成膜能够大规模、高效地进行分子分离的关键。具有坚硬的工程孔结构的材料通过提供熵调节的选择性增加了额外的自由度来制造先进的膜。可扩展性--高效、经济地将膜包装成实用组件的能力--是膜材料筛选中需要考虑的一个关键但往往被忽视的因素。在这篇进展文章中，我们重点介绍了基于这些刚性特征的可伸缩薄膜材料的持续发展，并确定了用于气体和液体应用的未来机会。这些先进的材料为超越现有材料和方法的新一代膜工艺打开了大门。
Materials research is key to enable synthetic membranes for large-scale, energy-efficient molecular separations. Materials with rigid, engineered pore structures add an additional degree of freedom to create advanced membranes by providing entropically moderated selectivities. Scalability - the capability to efficiently and economically pack membranes into practical modules - is a critical yet often neglected factor to take into account for membrane materials screening. In this Progress Article, we highlight continuing developments and identify future opportunities in scalable membrane materials based on these rigid features, for both gas and liquid phase applications. These advanced materials open the door to a new generation of membrane processes beyond existing materials and approaches.
