Abstract

The authors report considerable charge injection into thin films of cross-linked polyethylene (XLPE) from evaporated gold electrodes at DC-field strengths as low as 10⁶ V/m and commencing around 15°C. Injection was observed in samples cross-linked by three different processes. Comparison of thermally stimulated luminescence and dynamic mechanical thermal analysis data for XLPE and low-density polyethylene suggests that cross-linking suppresses the formation of intrinsic electron traps in the chain fold regions close to the surface of the crystalline lamellae
