The composite hydrogel membranes based on 2-hydroxyethyl methacrylate (HEMA)
and PVP copolymers modified by a thin layer of PA-6/PVP mixture using the diffusion
deposition from the solution were synthesized. The surface adsorption has been determined
depending on the hydrogel nature and the modifying polymer compositions as well as the
holding time of hydrogel film in the modifying solution. The influence of the surface
adsorption of PA-6/PVP mixture on the physical and mechanical properties of the synthesized
films composition membranes has been investigated.
