This paper reports observations of charge packets in nanostructured epoxy flat specimens with a filler content of 3% and 5%. These packets, behaving as solitons, accumulate very quickly close to the counter electrodes as heterocharge, due to the partially-blocking effect of the specimen/electrode interfaces. The base material, on the contrary, behaves differently: no charge pulses cross the insulation, showing instead a significant homocharge build up. However applying a compression of about 300 kPa to the base material specimen allows a significant amount of heterocharge to begin to accumulate, meaning that the fast charge pulse transport mechanism described above has been incepted.

Abstract
This paper reports observations of charge packets in nanostructured epoxy flat specimens with a filler content of 3% and 5%. These packets, behaving as solitons, accumulate very quickly close to the counter electrodes as heterocharge, due to the partially-blocking effect of the specimen/electrode interfaces. The base material, on the contrary, behaves differently: no charge pulses cross the insulation, showing instead a significant homocharge build up. However applying a compression of about 300 kPa to the base material specimen allows a significant amount of heterocharge to begin to accumulate, meaning that the fast charge pulse transport mechanism described above has been incepted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
