尽管纳米多孔膜在海水淡化中引起了人们的广泛关注，但构建具有较高截留率和高渗透性的纳米多孔膜以实现高效的海水淡化过程仍然具有挑战性。本研究中，高渗透性的纳米多孔膜在葡萄糖和多巴胺的多种功能的辅助下，通过与1,3,5-苯三甲酰三氯（TMC）的界面反应来制备。葡萄糖的小分子（0.66 nm）具有高亲水性，可以扩散到膜内部进行有效反应，确保结构完整性。本文中新型超薄（44 nm）纳滤（NF）膜在5 bar（1 bar = 10⁵ Pa）的压力下具有超高的Na₂SO₄通量及优异的 Na₂SO₄（66.5 L∙m⁻²∙h⁻¹, 97.3%）和MgSO₄（63.0 L∙m⁻²∙h⁻¹, 92.1%）截留率，其性能远优于基于天然产物的NF膜的性能。该膜表现出优异的长期稳定性，以及卓越的酸碱稳定性和抗污染能力。这项基于膜材料和结构的设计为超越现有膜材料分离膜打开了新的大门。

Although nanoporous membranes are of great interest in desalination, it is still challenging to construct highly permeable nanoporous membranes with excellent rejections for an efficient desalination process. In this work, highly permeable nanoporous membranes were built from renewable resources, assisted by the versatile functions of glucose and dopamine, with coupling reactive groups via interfacial reaction with 1,3,5-benzenetricarbonyl trichloride (TMC). The small molecules (0.66 nm) of glucose, which have high hydrophilicity, can diffuse into the membrane for an effective reaction to ensure structural integration. Our novel ultrathin (~44 nm) nanofiltration (NF) membrane exhibits ultra-high Na₂SO₄ flux and excellent rejection of Na₂SO₄ (66.5 L∙m⁻²∙h⁻¹, 97.3%) and MgSO₄ (63.0 L∙m⁻²∙h⁻¹, 92.1%) under a pressure of 5 bar (1 bar = 10⁵ Pa) which is much superior to the performance of natural-product NF membranes. The membrane demonstrates excellent long-term stability, as well as tremendous acid-base and alkali-base stability and high anti-pollution capacity. The designed membrane materials and architecture open a new door to biopolymer-based separation membranes beyond existing membrane materials.
