STUDY OF FAST ELECTRON IRRADIATION EFFECT ON THE STRUCTURE AND SURFACE OF POLYAMIDE/ POLYETHYLENE/ETHYLENE VINYL ACETATE FILM MATERIAL USING THE UELR 10-10-40 PLANT
Abstract
Radiation effect on the PA/PE/Eva film material with a thickness of 55 μm was investigated at theBurnazyanCenterusing radiation processing plant (RPP) with the UELR‑10–10–40 accelerator at 10 MeV. Polymer films were irradiated with doses of 0 to 18 kGy. The study of IR spectra showed that when processing the PA/PE/Eva film with fast electrons with a dose of up to 18 kGy using the UELR10–10–40 plant with a power of 10 MeV the number of functional -CH3 and -NHgroups in the IR spectra changes to 0.0060 relative units with radiation doses of 12 to 18 kGy, which leads to degradation of the sample and its crosslinking simultaneously. Using confocal laser microscopy, it was demonstrated that after irradiation of PA/PE/Eva sample with doses of 18 kGy, the surface of the film becomes smooth in РА layer and in Eva layer, and a spot thinning of the sample occurs. These characteristics may cause a change in the barrier properties of the film material and affect the shelf life of food in a packaging.
