Effect of interface chemistry on charge injection and trapping in polyethylene blend
Effect of interface chemistry on charge injection and trapping in polyethylene blend
The electrical characteristics of dielectric surfaces are important in determining overall electrical performance. In this work, one surface of polyethylene blend films was treated at a high temperature for various times to modify the local chemistry. Confocal Raman microprobe spectroscopy was subsequently employed to detect signatures of ageing at the surface and through bulk of specimens. The pulsed electro-acoustic (PEA) method was used to investigate charge injection and trapping processes. The results demonstrate that chemical changes resulting from ageing cause dramatic and abrupt changes in the charge transport dynamics within the system.

Abstract
The electrical characteristics of dielectric surfaces are important in determining overall electrical performance. In this work, one surface of polyethylene blend films was treated at a high temperature for various times to modify the local chemistry. Confocal Raman microprobe spectroscopy was subsequently employed to detect signatures of ageing at the surface and through bulk of specimens. The pulsed electro-acoustic (PEA) method was used to investigate charge injection and trapping processes. The results demonstrate that chemical changes resulting from ageing cause dramatic and abrupt changes in the charge transport dynamics within the system.
