A significant impact of the electron irradiation intensity and the temperature of initial solutions on the processes of polymer radiation crosslinking is experimentally revealed and analyzed. The hydrophily of crosslinked hydrogels is demonstrated to depend more strongly on the exposure dose than on the gel composition. The optimal intervals of radiation doses and polymer concentrations, at which the radiation-crosslinked hydrogel satisfies requirements for medical dressing materials are determined. |
