Implication

Experimental analysis reveals temperature-dependent dielectric relaxation peaks in low-density polyethylene, indicating distinct bulk dipolar and carrier hopping mechanisms.

Key Points

To investigate the charging and discharging current transients in low-density polyethylene across wide ranges of electric fields and temperatures.
Measured charging and discharging transients in low-density polyethylene (0.918 g/cm³) across temperatures ranging from 113 K to above 273 K.
Tested samples across varying electric fields, sample thicknesses, and electrode materials to evaluate isochronal current responses.
Identified two broad isochronal current peaks at 138 K (gamma-relaxation) and 203 K in the 113–273 K range, attributed to dipolar processes during bulk molecular relaxations.
Observed absorption currents above 273 K that are consistent with a charge carrier hopping transport mechanism.
