Ellipsometry - Contains experimental results of dry and wet ellipsometry measurements. Fitted quantities are: model layer thickness of SiO2 and PEM layer (nm), A (-) and B (microm^2) Cauchy model parameter, effective medium approximation (%). 
FiltrationExperiments - Contains experimental results of pure water permeability measurements, polyethylene glycol (PEG) retention measurements, and single salt retention measurements. Measured quantities are: active fiber length (m), average [inlet and outlet] pressure (bar), permeate mass (g) [filled beaker-empty beaker], permeation time (s), feed and permeate conductivity (microS/cm), feed and permeate pH (-), MWCO (g/mol) [based on GPC data].
GPC - Contains experimental results of gel permeation chromatography measurements. Determined quantities: signal intensity (a.u.) and molecular weight [based on residence time and calibration curve] (g/mol).
ZetaPotential - Contains experimental results of Zeta Potential measurements. Determined quantities: pH [-] and Zeta Potential [mV].
