Data underlying the publication: Asymmetric polyelectrolyte multilayer nanofiltration membranes: Structural characterisation via transport phenomena.

This dataset is meant as supplementary information to the publication: Junker, Moritz A., et al. "Asymmetric polyelectrolyte multilayer nanofiltration membranes: Structural characterisation via transport phenomena." Journal of Membrane Science 681 (2023): 121718.In this work, the fabrication and performance of asymmetric polyelectrolyte multilayer based nanofiltration membranes were analysed by a combination of experimental filtration studies and theoretical transport modeling. Experimental methods applied for membrane characterisation include pure water permeability, single salt retention, polyethylene glycol retention, and ternary ion retention. Additionally, polyelectrolyte multilayers were studied on a model surface via spectroscopic ellipsometry. Based on experimental results, different pore flow models were parametrised to describe and predict the filtration behaviour.The dataset contains all relevant data for the study. This includes experimental and theoretical results. More information on the specific files can be found within the README.txt file.

本数据集作为以下学术论文的补充信息发布：Junker, Moritz A. 等人所著《不对称聚电解质多层膜纳滤膜：基于输运现象的结构表征》，发表于《膜科学学报（Journal of Membrane Science）》681卷（2023年），文章编号121718。
本研究通过实验过滤测试与理论输运建模相结合的手段，分析了基于不对称聚电解质多层膜（polyelectrolyte multilayer）的纳滤膜（nanofiltration membrane）的制备工艺与性能。用于膜表征的实验方法包括纯水渗透性测试、单盐截留率测试、聚乙二醇（polyethylene glycol）截留率测试以及三元离子截留率测试。此外，本研究还借助光谱椭偏术（spectroscopic ellipsometry）在模型表面对聚电解质多层膜开展了表征研究。基于实验结果，研究人员对多种孔隙流动模型（pore flow model）进行了参数化拟合，以描述并预测膜的过滤行为。
本数据集涵盖本研究的全部相关数据，包含实验与理论研究结果两部分。关于各具体文件的详细说明，请参阅README.txt文件。
