Dielectric Spectroscopy and Thermally Stimulated Depolarization Current investigations in Low Density Polyethylene

The dielectric behavior and the molecular dynamics of pure low density polyethylene films are studied by dielectric spectroscopy and thermally stimulated depolarization current techniques. Three dielectric relaxations processes are observed, analyzed and discussed in terms of their activation energies, shapes, and temperature dependences of relaxation times and dielectric strengths.
