在这里，我们介绍了一个简单的，可扩展的，技术相关的战略，以可控的方式制造带电多孔聚合物膜（CPM）。通过合理选择聚离子液体（PIL）中的阴离子，可以很好地控制CPM的孔径和孔结构。通过对所制备的碳膜进行形貌保持碳化，可以方便地制备杂原子掺杂的分级多孔碳膜。这些HCM作为光热膜，在太阳能海水淡化方面表现出优异的性能，代表了构建用于便携式水生产技术的先进功能纳米材料的有前途的策略。
Herein, we introduce a straightforward, scalable, and technologically relevant strategy to manufacture charged porous polymer membranes (CPMs) in a controllable manner. The pore sizes and porous architectures of CPMs are well-controlled by rational choice of anions in poly(ionic liquid)s (PILs). Continuously, heteroatom-doped hierarchically porous carbon membrane (HCMs) can be readily fabricated via morphology-maintaining carbonization of as-prepared CPMs. These HCMs, as photothermal membranes, exhibited excellent performance for solar seawater desalination, representing a promising strategy to construct advanced functional nanomaterials for portable water production technologies.
