Charge trapping in gamma irradiated low-density polyethylene
Abstract
The influence of gamma irradiation in two different atmospheres, air and distilled water on charge trapping in LDPE has been studied through dielectric loss (tan delta) analysis in the temperature range from 25 to 325 K and using thermally stimulated discharge current (TSDC) measurements. The radiation induced oxidation was observed using IR spectroscopy. The intensity and the position of the gamma and beta dielectric relaxation maxima were correlated with maxima of TSDC measurements, and found to be strongly dependent upon the changes in the microstructure of the amorphous phase and on the surface of the crystallites induced by oxidation and crosslinking.
