Abstract
The influence of temperature from 298 K to 353 K on the electrical conducti on of low-density polyethylene is reported. Conduction current and differen tial scanning calorimetry (DSC) measurements show a correlation between the structural change due to the temperature treatment and the change in the a ctivation energy of the conduction mechanism involved. When the temperature is greater than 318 K, an activation energy decrease from 0.94 eV to 0.68 eV and a DSC exothermic peak are observed. This temperature threshold is co rrelated with a facilitated detrapping of charges stored during polarizatio n.
