TL;DR: In this paper, the application of the pore-filling concept yielded aromatic hydrocarbon selective composite membranes with an average pore size of about 9 nm for the development of pervaporation separation phases prepared in situ by photo-initiated graft copolymerization in water.

TL;DR: In this article, a polyelectrolyte-surfactant complex (PELSC) membrane was prepared by the interaction of the anionic groups of Na-CS or sulfoethyl cellulose (SEC) with different types of cationic surfactants.

TL;DR: In this article, the surface properties of two polyelectrolyte complex (PELC) membranes based on polyanionic sulfoethylcellulose (SEC) and polycationic poly[dimethyl(diallyl)ammonium chloride] (pDMDAAC) or cationic benzyl(dodecyl)dimethylammonium (BDDDMAC) were studied by means of contact angle measurements in different media, XPS photoelectron spectroscopy and tangential streaming potential measurements.

TL;DR: In this article, the performance and selectivities of polyelectrolyte complex membranes based on sodium cellulose sulfate as a polyanion and various types of cationic components -poly(dimethyldiallylammonium chloride), poly(ethyleneimine hydrochloride) as polycations; or (2-(N -undecylamidocarbonyl)-ethyl)-dimethylbenzyl ammonium chloride, N -dodecylpyridinium chloride as cationi surfactants -were prepared.

TL;DR: In this paper, the surface properties of polyelectrolyte complex membranes based on sodium cellulose sulfate and poly(dimethyldially-lammonium chloride) were studied by means of XPS photoelectron spectroscopy (ESCA), contact angle and tangential streaming potential measurements.
