Abstract (EN)The paper describes the synthesis process of hydrogel materials based on polyvinyl alcohol (PVA) and polyethylene glycol (PEG) filled with titanium-dioxide particles in concentrations of 1%, 0.1%, and 0.01% mass. The size distribution of titanium dioxide particles is obtained by the method of dynamic light scattering. To obtain data on the structure of the obtained materials before and after electron irradiation, wide-angle radiography is used, the results of which reveal a possible interplay between the titanium-dioxide particles and the polymer matrix. Tensile tests show a decrease in the tensile strength and strain to break of the hydrogel with increasing titanium-dioxide concentration. PVA–PEG–TiO2 hydrogels do not show antimicrobial activity against reference strains of Staphylococcus aureus and Escherichia coli.
