[en] Measurements of electric conductivity of gamma-rays irradiated low density polyethylene (LDPE) were conducted through uniaxial elongation by tensile stress. Inflated films with 50 μm thickness were pre-irradiated to 2 x 10⁵ Gy in vacuum to produce a cross-link. Uniaxial elongation was effected at 20 C with a drawing rate of 7 mm/min. Films were fixed to metallic frames after elongation to maintain tension. As a result of elongation the rate of conduction current decay was rapid, while the rates of electric conductivity and apparent conduction activation energy decreased. Current was observed in the high electric field and an assumption of space-charge-limited current was made. The suppression of microbrownian movement in amorphous parts and the increase of interfaces between amorphous and crystalline parts due to elongation were attributed to this observed behavior.
