Abstract

Exploring organic solvent nanofiltration (OSN) membranes with improved permeability and selectivity is imperative to realize energy efficient separation in industry practice. Herein, we fabricated mixed matrix membranes (MMMs) based on Poly(1-trimethylsilyl-1-propyne) (PTMSP) and a variety of porous polymer networks, including p-DCX, p-DCX-NH₂, PAF-1 and PAF-1-NH₂, via a simple drop-casting method. These hyper-crosslinked additives, which are compatible with the polymer matrix, were employed to create additional pathways for solvent transport, reduce defect cavities to enhance solute rejection, and inhibit the migration of polymer chains. The methanol permeance of MMMs increased by as much as 74 % and the retention of Rose Bengal (MW:1017 g‧mol⁻¹) was improved from 95.2 % to 99.2 %. In contrast to the pure PTMSP membrane, the MMMs displayed superior performance and OSN stability during 100 h of continuous operation (methanol permeation loss rate decreased from 35.6 % to 11.3 %). This study provides insight for the benefits of additives with porous polymer networks for OSN membranes, and is favor for the wide application of these exciting membrane materials.

多孔聚合物网络中加入了具有增强有机溶剂纳滤性能的PTMSP膜

探索具有高渗透性和选择性的有机溶剂纳滤（OSN）膜是实现工业高效分离的必要条件。本文采用滴铸法制备了基于聚（1-三甲基硅基-1-丙炔）（PTMSP）和多种多孔聚合物网络（p-DCX、p-DCX- nh2、PAF-1和PAF-1- nh2）的混合基质膜（MMMs）。这些与聚合物基体相容的超交联添加剂被用来为溶剂运输创造额外的途径，减少缺陷腔以增强溶质排斥，并抑制聚合物链的迁移。MMMs的甲醇透过率提高了74 %，粉红玫瑰（MW:1017 g·mol−1）的保留率由95.2% %提高到99.2% %。与纯PTMSP膜相比，MMMs在连续运行100 h时表现出更优异的性能和OSN稳定性（甲醇渗透损失率从35.6 %下降到11.3 %）。本研究为OSN膜提供了具有多孔聚合物网络的添加剂的好处，有利于这些激动人心的膜材料的广泛应用。

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
