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.
材料研究是实现用于大规模、节能的分子分离的合成膜的关键。具有刚性、工程化孔结构的材料通过提供熵调节的选择性，为创建先进的膜增加了一个额外的自由度。可扩展性 - 即有效地、经济地将膜包装到实际模块中的能力 - 是膜材料筛选中需要考虑的一个关键但经常被忽视的因素。在这篇进展文章中，我们强调了基于这些刚性特征的气体和液相应用的可扩展膜材料的持续发展，并确定了未来的机会。这些先进材料为超越现有材料和方法的新一代膜工艺开辟了道路。
