Data underlying the publication: Relating uncharged solute retention of polyelectrolyte multilayer nanofiltration membranes to effective structural properties.

This dataset is meant as supplementary information to the publication: Junker, Moritz A., et al. "Relating uncharged solute retention of polyelectrolyte multilayer nanofiltration membranes to effective structural properties." <em>Journal of Membrane Science </em>668 (2023): 121164.In this work, the fabrication and performance of 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, MgSO4 retention, polyethylene glycol retention. The selective membrane layer was imaged using Field Emission Scanning Electron Microscopy. Based on experimental results, different pore flow models were parametrised to describe 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.

本数据集作为下述学术出版物的补充信息：Junker, Moritz A. 等人在《Journal of Membrane Science》（膜科学期刊）2023年第668卷第121164页发表的论文《聚电解质多层纳滤膜的中性溶质截留性能与有效结构性质的关联（Relating uncharged solute retention of polyelectrolyte multilayer nanofiltration membranes to effective structural properties）》。本研究通过实验过滤测试与理论传输建模相结合的方法，分析了聚电解质多层（polyelectrolyte multilayer）基纳滤膜（nanofiltration membrane）的制备工艺与性能表现。用于膜表征的实验方法包括纯水渗透率测定、硫酸镁（MgSO₄）截留率测试以及聚乙二醇（polyethylene glycol, PEG）截留率测试。研究采用场发射扫描电子显微镜（Field Emission Scanning Electron Microscopy, FESEM）对选择性膜层进行成像表征。基于实验结果，研究人员对多种孔隙流动模型进行参数化拟合，以描述其过滤行为。本数据集涵盖本研究的全部相关数据，包含实验与理论结果两类。各具体文件的详细说明，请参见README.txt文件。
