All-Poly(ionic liquid) Membrane-derived Porous Carbon Membranes: Scalable Synthesis and Application for Photothermal Conversion in Seawater Desalination
摘要：
本文首先介绍了一种简单的、可扩展的和技术相关的策略，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作为光热膜表现出优异的性能，太阳能海水淡化，代表了一个有前途的战略，构建先进的功能纳米材料的便携式水生产技术。
英文摘要：
Herein we firstly 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 being as photothermal membranes exhibited excellent performance for solar seawater desalination, representing a promising strategy to construct advanced functional nanomaterials for portable water production technologies.
