摘要

高通量和选择性膜是提高水净化纳滤工艺能效的关键组成部分。在此,我们报告了由用于纳滤的特罗格碱组成的高通量聚酰胺薄膜复合(TFC)膜。特罗格碱二胺(TBD)是作为界面聚合的水相单体合成的。利用热学、光谱和显微分析对基于 TBD 的聚酰胺进行了详细表征。值得注意的是,与传统聚酰胺化学(即 MPD-TMC)相比,TBD 基聚酰胺(命名为 TBD-TMC)的 V 形刚性特罗格基图案具有更高的微孔率和更大的孔径。因此,与 MPD-TMC 膜相比,TBD-TMC 膜的透水性提高了 570%,同时具有高达 91% 的中等盐排斥率,优于大多数已报道的纳滤膜。此外,TBD-TMC 膜还表现出很高的一价/二价离子选择性(NaCl/Na2SO4 分离可达 7.0),这可能是尺寸排斥和电荷排斥的共同作用的结果。这项工作凸显了特罗格基主题作为一种新型二元胺单体的潜力,可用于界面聚合膜以调整其微孔结构。

High-flux polyamide thin-film composite membranes consisting of Tröger’s base motif with enhanced microporosity for nanofiltration
High-flux and selective membranes are key components to improving the energy efficiency of nanofiltration processes for water purification. Herein, we report high-flux polyamide thin-film composite (TFC) membranes consisting of Tröger’s base for nanofiltration. Tröger’s base diamine (TBD) was synthesized as an aqueous phase monomer for interfacial polymerization. Detailed characterization of TBD-based polyamides was performed using thermal, spectroscopic, and microscopic analyses. Notably, the V-shaped and rigid Tröger’s base motif rendered TBD-based polyamide (named TBD-TMC) features with enhanced microporosity as well as an enlarged pore size compared to conventional polyamide chemistry (i.e., MPD-TMC). As a result, the TBD-TMC membrane exhibited a 570% improvement in water permeance compared to MPD-TMC membranes while exhibiting moderate salt rejection up to 91%, outperforming most reported nanofiltration membranes. Also, the TBD-TMC membrane exhibited high monovalent/divalent ion selectivity (∼7.0 for NaCl/Na2SO4 separation), which may have resulted from the combined effects of size exclusion and charge repulsion. This work highlights the potential of Tröger’s base motif as a new diamine monomer for interfacially polymerized membranes to tune their microporous structures.
