Abstract
Thermally stimulated current (TSC) / Thermally stimulated luminescence (TSL) United Spectra in polyethylene samples (with and without the free radical scavenger (FRS)) during electrical aging process were measured. The variations of density of traps and combination centers in polyethylene during the aging process were investigated through those spectra, then the variation of molecular motion of polyethylene was discussed. From the calculation of apparent amounts of traps and luminescence centers, it is shown that the amount of variation of trap centers was much obvious than that of luminescence centers during the aging process. Thus it could be deduced that this kind of FRS inhibited electrical aging of polyethylene through suppressing the produce of traps, especially deeper traps. It is noteworthy that this deduction mentioned above is much more valuable for improving electrical strength of polymer further.
