Abstract

The surface properties and the functional-chemical composition of plasticized cellulose triacetate (TAC) films subjected to electron-beam treatment in the absorbed dose range of D = 25–150 kGy have been studied. It has been shown that a decrease in the contact angle of water on the films at D = 25–75 kGy is caused by an increase in the concentration of carboxyl and hydroxyl groups formed during the radiolysis of the plasticizer dibutyl phthalate. A high adhesive strength of gelatin emulsion layers obtained on the films irradiated at D = 50 kGy is due to the formation of chemical bonds between gelatin amino groups and TAC carboxyl groups.
