Data underlying the publication: Effects of feed solution pH on polyelectrolyte multilayer nanofiltration membranes.

This dataset is meant as supplementary information to the publication: Junker, Moritz A., et al. "Effects of Feed Solution pH on Polyelectrolyte Multilayer Nanofiltration Membranes." ACS Applied Polymer Materials 5 (2023): 355-369.In this work, the influence of solution pH during filtration on the separation performance of polyelectrolyte multilayer based nanofiltration membranes was studied. Experimental methods applied for membrane characterisation include pressure-driven filtration (pure water permeability, polyethylene glycol retention, single salt retention), Zeta Potential measurements over a range of pH values, and spectroscopic ellipsometry measurements (dry and wet conditions).The dataset contains all relevant data for the study. More information on the specific files can be found within the README.txt file.
