Abstract

Organic solvent nanofiltration (OSN) is a green, efficient and energy-saving new separation technology. However, it is exigent to membrane materials with both good soluble processability and solvent resistance, as well as methods for preparing composite membranes that combine high accuracy and stability. In this work, a novel polyaryletherketone containing phenylamine structure (PEK-PA) was prepared and used to fabricate a novel solvent resistant composite membrane via strategies of chemical crosslinking and polymer filling into the surface pores of the membrane. The crosslinking between PEK-PA and trimesoyl chloride improves the solvent resistance of the membrane and the strategy of polyamide filling improves the separation accuracy of the membrane. The prepared OSN membranes exhibit exceptional separation accuracy, with a molecular weight cut-off within the range of 214 g mol−1 to 383 g mol−1. More importantly, the prepared membranes exhibit higher stability than the thin-film-composite membranes prepared by interfacial polymerization, which was demonstrated by a designed reverse pressure experiment. The prepared membranes can be continuously operated in DMF for 60 h, thereby demonstrating their excellent stability even for harsh polar aprotic solvents. Therefore, this work presents a novel solvent resistant membrane material with potential applications for OSN.

用于有机溶剂纳滤的高稳定性聚酰胺填充交联聚芳醚酮复合膜
有机溶剂纳滤(OSN)是一种绿色、高效、节能的新型分离技术。然而,这就要求膜材料既要有良好的可溶性加工性和耐溶剂性,又要有兼具高精度和高稳定性的复合膜制备方法。本研究制备了一种新型的含苯胺结构的聚芳醚酮(PEK-PA),并通过化学交联和聚合物填充膜表面孔隙的策略制备了一种新型的耐溶剂复合膜。PEK-PA 与三甲基甲酰氯之间的交联提高了膜的耐溶剂性,而聚酰胺填充策略则提高了膜的分离精度。所制备的 OSN 膜具有极高的分离精度,分子量截止范围在 214 g mol-1 至 383 g mol-1 之间。更重要的是,制备的膜比通过界面聚合法制备的薄膜复合膜具有更高的稳定性,这一点已通过设计的反向压力实验得到证实。所制备的膜可在 DMF 中连续运行 60 小时,从而证明了其即使在苛刻的极性钝化溶剂中也具有出色的稳定性。因此,这项研究提出了一种新型耐溶剂膜材料,有望应用于 OSN。

期刊介绍: The Journal of Membrane Science is a publication that focuses on membrane systems and is aimed at academic and industrial chemists, chemical engineers, materials scientists, and membranologists. It publishes original research and reviews on various aspects of membrane transport, membrane formation/structure, fouling, module/process design, and processes/applications. The journal primarily focuses on the structure, function, and performance of non-biological membranes but also includes papers that relate to biological membranes. The Journal of Membrane Science publishes Full Text Papers, State-of-the-Art Reviews, Letters to the Editor, and Perspectives.
