The pervaporation properties of the membranes were studied for the separation of aqueous alcohol (ethanol, propan-2-ol) mixtures of different compositions. When the mixtures to be separated consist of less than 15 wt % water in propan-2-ol, the membranes composed of polyelectrolytes with the same molar fraction of ionogenic groups (-NH3+ for chitosan and -SO3\u2212 for sulfoethylcellulose) show high permselectivity (the water content in the permeate was 100%). Factors affecting the structure of a non-porous layer of the polyelectrolyte complex formed on the substrate surface and the contribution of that complex to changes in the transport properties of membranes are discussed. The results indicate significant prospects for the use of chitosan and sulfoethylcellulose for the formation of highly selective pervaporation membranes.<\/jats:p>","DOI":"10.3390\/molecules22122227","type":"journal-article","created":{"date-parts":[[2017,12,14]],"date-time":"2017-12-14T12:35:45Z","timestamp":1513254945000},"page":"2227","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Two-Ply Composite Membranes with Separation Layers from Chitosan and Sulfoethylcellulose on a Microporous Support Based on Poly(diphenylsulfone-N-phenylphthalimide)"],"prefix":"10.3390","volume":"22","author":[{"given":"Svetlana","family":"Kononova","sequence":"first","affiliation":[{"name":"Institute of Macromolecular Compounds of the Russian Academy of Sciences, Bolshoi pr.
