Abstract
In these study membranes based on Poly (sodium 4-styrene sulfonate) (PSS) and Poly (diallyl dimethyl ammonium chloride) (PDADMAC) were obtained by the method proposed by J. Kamp et al. [1]. The membrane preparation is based on interpolymer complexes formation in a water medium. The influence of the concentration of polymers (20 and 25 wt. %) and the thickness of the forming knife (200 and 400 μm) on the morphological properties of the formed membranes were studied. It was established that the average pore size for membranes based on 25% solutions is higher (107 ± 4 nm) than for 20% solutions (94 ± 3 nm). The pore structure in the samples is spongy (Fig.1) and does not depend on concentration or thickness.
