“…According to [20], a decrease in microhardness is mainly associated to the softening of the crystalline region. An increase in the thickness of amorphous region -and therefore a decrease in crystallinity -will result to a decrease of the breakdown strength of the insulating material [21,22]. On the other hand, working with poly (ether ether ketone) -PEEK, which is a high temperature insulating thermoplastic, it was observed that the breakdown strength decreased by increasing the crystalline/amorphous ratio of the polymer [23,24].…”

“…Experiments with polyethylene films indicated that the breakdown strength decreases with increasing temperature. As an explanation, it was put forward the electron thermal runaway in localized electron system caused by the interaction with conduction electrons [21].…”

“…In [55], polyethylene terephthalate (PET) showed a decrease of breakdown strength going up from 33 o C to 73 o C because ofas the authors claimed -the activation of thermal breakdown pathways [55]. Such an approach is not radically different from the interpretation given in [21].…”

Thermal ageing of Epidian-2 epoxy resin results in quenching and decrease in energetic depth of dopant thermoluminescence (TL) centres. The existing correlation between the depths or TL centres and the contents of methylene and methyl groups suggests that these groups are the cause of the dopant TL peaks. The SiO, filler exhibits catalytic effects and restricts the formation of methylene and methyl groups in the resin. EinfluP der thermischen Alterung auf die Thermolumineszenz eines EpoxidharzesBei der thermischen Alterung des Epoxidharzes Epidian-2 wurde eine Abnahme der Thermolumineszenz und eine Verringerung der energetischen Tiefe der Dotierungszentren gefunden. Aus der Korrelation zwischen der energetischen Tiefe der Thermolumineszenzzentren und dem Gehalt an Methyl-und Methylengruppen wird darauf geschlossen, da13 diese Gruppen die Ursache fur die Thermolumineszenzpeaks sind. Der SO,-Fullstoff hat einen katalytischen EinfluW und schrankt die Bildung von Methyl-und Methylengruppen in dem Harz cin.

SynopsisStep voltage transient current studies have been made in cellulose acetate films as a function of field and thickness. A logarithmic plot (Scherr-Montroll plot) of the transient current vs. time gives a knee at a time t~, which is interpreted as the transit time of the charge carrier. The value of the carrier mobility has been estimated to be 3.9 X cm2.V-l.s-' in cellulose acetate film. The carrier mobility in 'iodine-doped (2% w/w) cellulose acetate film has also been determined from ScherMontroll plot and is found to be 3.3 X cm2.V-'-s-'.
