“…This fact is often discussed at investigations by TSC and TSDC methods [16,17], where the dielectric is preliminary exposed to the electric field of high strength. In this case, the injection of carriers from the electrode into the polymer is possible and, consequently, the electrode material should affect this process.…”

“…As the temperature increases above 420 K, the spectra show a sharp increasing current which is a common feature to many polymers. [8,28] The exact origin for the increasing current is still debated. Sometimes the current is called spontaneous current.…”

The chain segment motion, charge trapping and detrapping in g-irradiated nylon 1010 films (doses in the range 0 -2,000 kGy were used) have been investigated by means of thermally stimulated depolarization current (TSDC). There are three current peaks (named a, r 1 and r 2 , respectively) in the TSDC spectra, corrected by spontaneous current, above room temperature. By analyzing the characteristic parameters of the three peaks, it is found that the chain segment motion in the amorphous regions becomes more difficult at low irradiation dose (,100 kGy) and then becomes easier with further increasing irradiation dose. The stability of the traps at the crystalline-amorphous interfaces increases at low irradiation dose (,500 kGy) and then decreases with further increasing irradiation dose; the irradiation promotes the creation of traps and the stability of traps in the crystalline regions.

“…Measurements of absorption currents and thermostimulated currents have shown the influence of the electrode metal on the conduction current in PET and on the space charge accumulation [1][2][3]. Electronic beam-induced depolarization experiments have provided the polarity and localization of these injected space charges [1].…”

Using the LIPP method, negative homocharges have been observed in PET sheets after a few hours poling under 6kV/mm DC at 60°C. This observation was made with various electrode metals: gold (Au), aluminium (Al) and silver (Ag). With gold electrodes, the injection is much slower than with the other two metals. Furthermore, the gold metallization is the only one leading to the injection of positive space charges in the same conditions. Similarly, at 55°C under 7kV/mm, positive homocharges have been observed in epoxy sheets only with gold-deposited electrodes and not with aluminium electrodes.
