Investigation of charge injection threshold field in epoxy resin

Investigation of charge injection threshold field in epoxy resin
Investigation of charge injection threshold field in epoxy resin
In this paper, space charge formation in epoxy resin has been measured at different applied electric fields using the pulsed electroacoustic technique to reveal the charge injection threshold field. The influence of electrode material on the charge injection has also been investigated. It has been found that the threshold field value for negative charge injection is much lower than that of positive charges, and electrons are the dominant type of charge carrier in epoxy resin. Compared with aluminium, the sample with gold electrode shows a higher threshold field value and lower amount of charge injection. This observation can be attributed to a higher work function of the gold.

Abstract

In this paper, space charge formation in epoxy resin has been measured at different applied electric fields using the pulsed electroacoustic technique to reveal the charge injection threshold field. The influence of electrode material on the charge injection has also been investigated. It has been found that the threshold field value for negative charge injection is much lower than that of positive charges, and electrons are the dominant type of charge carrier in epoxy resin. Compared with aluminium, the sample with gold electrode shows a higher threshold field value and lower amount of charge injection. This observation can be attributed to a higher work function of the gold.
