resulting in a global sustainability crisis. Membrane desalination is a promising method to produce fresh water from saline waters. However, Zhi Li,研究人员在新开发的多孔铜中空纤维支撑的烷炔-芘共轭框架膜上实现了超快速脱盐, 在该研究中,其渗透性至少比商用聚合物膜高1个数量级,传统膜经常遇到与低渗透率相关的挑战。
导致全球可持续性危机, negatively impacting energy efficiency and water productivity. Herein, and the graphene-like hydrophobic surface of conjugated frameworks exhibits complete salt exclusion. The simulations also confirm that the intraplanar pores of frameworks are impermeable for water and ions.

Experimental and theoretical investigations suggest that the large aspect ratio of membrane pores and the high evaporation area contribute to the high flux。
