The cationic charged chitosan and the weak polyacid poly(ethylene-alt-maleic acid) are used to build polyelectrolyte multilayers (PEMs). To study rotational dynamics of polymer backbone in swollen state PEMs using electron paramagnetic resonance spectroscopy, a nitroxide spin-label is covalently attached polyacid. It found that spectra with even number layers show superposition two spectral com...

Polyelectrolyte multilayers (PEMs) are highly promising materials as selective separation layers on the inside of hollow fiber membranes. We investigate forward osmosis (FO) performance poly(4-styrene sulfonate) (PSS)/poly(allylamine) (PAH)- and PSS/poly(ethylene imine)-based PEM membranes apply different draw solutions. The show properties, demonstrated by their retention behavior under nanofi...
