Peculiarities of hydrogel – polyamide composition membranes formation

Abstract

Quality composition of the subphase for modification of hydrogel membranes by ultra thin polyamide layer is selected. It was designed the laboratory appliance which allows applying the surface layer of polyamide by direct contact of the hydrogel film with a thin layer of modifying solution. The compositional film membranes based on hydroxyethyl methacrylate cross-linking copolymers with polyvinylpyrrolidone and aliphatic polyamide are obtained.
