Files:

BMP: 
FESEM images of PEM membranes (PAH/PAA: 3 and 9 bilayers, PDADMAC/PSS: 3 and 9 bilayers).

Excel:
Experiments - Contains experimental results of pure water permeability measurements, MgSO4 retention measurements and polyethylene glycol (PEG) retention measurements. Measured quantities are: active fiber length (m), feed temperature (C), inlet and outlet pressure (bar), permeate mass (g) [filled beaker-empty beaker], permeation time (s), feed and permeate conductivity (microS/cm) [MgSO4 retention], retention based on GPC signal intensity (-) [PEG retention].
Model - Contains fitting results regarding pure water permeability, solution diffusion model, and pore flow models. Fitting parameters include their estimated uncertainty (95% confidence interval from nlparci function in Matlab).
GPCRaw - Contains raw data of GPC measurements. Determined quantities: signal intensity (a.u.) and molecular weight [from residence time using calibration curve] (g/mol). 

Matlab Scripts:
Fit - Matlab script used to fit different pore flow models to experimental data. Example case for PAH/PAA 10 BLs.
Plots - Matlab script used to make figures.
