Résumé

Thermo-stimulated depolarization current (TSDC) measurements have been performed on low density polyethylene (LDPE), a non polar polymer material. The aim is to develop the understanding of the conduction mechanisms at play in this material, and particularly to understand the effect of temperature and antioxidant presence. Variations of the TSDC experimental protocol (charging voltage, pre-heating temperature before quenching) are investigated. Furthermore, original measurements are also performed, aiming at driving the carriers outside the dielectric during the reheating rate. To do so, a relatively small voltage, positive or negative, is applied during the temperature ramp. Experimental results obtained with LDPE samples are interpreted with the help of a bipolar transport model.
