    Development of the forming technology of combined membranes based on hydrogel and polycaproamide
    (Видавництво Львівської політехніки, 2017-12-23) Baran, Nataliya; Melnyk, Yuriy; Grytsenko, Oleksandr; Yaculchak, Galyna; Shapoval, Catheryna; Lviv Polytechnic National University
    The technology of forming of composite polymer membranes by modifying the surface of hydrogels thru thin layer of polymer has been developed. The physical, mechanical properties and surface adsorption of composite membranes are determined. It was established that via variation of composite structures of hydrogel and modifying layers of composite membranes can be directed regulating of their physical and mechanical properties and surface adsorption of the obtained composite membranes.

    Regularities of films forming on the basis of polyamide-polyvinylpyrrolidone mixtures
    (Publishing House of Lviv Polytechnic National University, 2012) Suberlyak, Oleh; Baran, Nataliya; Gnatowski, Adam; Jaruga, Tomash; Melnyk, Yuriy
    Modification of polyamide-6 by polyvinylpyrrolidone with molecular mass of 12000±2000 has been carried out using their mixing in formic acid solution followed by solvent evaporation. The possibility of films permolecular structure control, physico-mechnical and thermophysical properties by treatment conditions after their formation has been established. У роботі проведено модифікацію поліаміду-6 полівінілпіролідоном із молекулярною масою 12000±2000 методом змішування їх у мурашинокислому розчині з наступним упарюванням розчинника. Встановлена можливість регулювання надмолекулярної структури, фізико-механічних і теплофізичних властивостей плівок від умов їх обробки після формування.
