Abstract
This study considers the possibility of using high-energy electrons (3.8 MeV, dose range of 46–200 kGy) for radiation-induced grafting of the polyethylene terephthalate ion-track membranes (PET ITMs) with the functional monomer of acrylic acid (AA). The effect of such factors as monomer concentration, dose, and average speed of the beam section of the accelerator conveyor was studied. The pristine and grafted samples of ion-track membranes were comprehensively studied by advanced physicochemical techniques. As a result of the studies, the optimal conditions for the radiation-induced grafting of PET ITMs with accelerated electrons were determined. A sufficiently high degree of grafting of AA while maintaining the mechanical strength of the polymer template were achieved for next conditions: the content of CuSO4 inhibitor is not more than 1%, the acrylic acid monomer concentration is not more than 10%, radiation dose in the range of 100–117 kGy.
