dc.description.abstractPolyelectrolyte complex membranes are materials based on oppositely charged polyelectrolytes that are typically soluble in water. Interaction between oppositely charged polyelectrolytes creates an insoluble substance that can form solids in aqueous environments. Such a process does not require organic solvents, and such an aqueous salt-dilution-induced phase separation process induces polyelectrolyte complexation through a pH or salinity switch [1]. Due to the low dielectric constant polyelectrolyte complex membranes are stable in organic solvents, which makes them suitable for a wider range of separation processes [2]. In this study membranes based on poly (sodium 4-styrene sulfonate) (PSS) and poly (diallyl dimethyl ammonium chloride) (PDADMAC) were obtained using the method proposed by J. Kamp et al. [1]. The investigation focused on assessing the impact of polymer concentration and forming knife thickness on the membrane properties.en_US
