摘要：
The effect of electron-beam irradiation on the surface properties and the parameters of the semicrystalline structure of biaxially oriented poly(ethylene terephthalate) (PET) films was studied. It was shown that the crystallinity and the surface tension of the irradiated films at the interfaces with isooctane and water vary in a nonmonotonic manner over the dose range D= 25–300 kGy. As the absorbed dose increases, the dispersion and polar terms of surface energy increase, exhibiting an extremum as a result of the competing chain crystallization and amorphous-phase formation processes, as well as oxidative degradation and crosslinking of PET samples.
