Abstract :
The authors show that large amounts of charge accumulate near the interface in the laminate samples, resulting in an increase of the electric field in the PE layers. This may enhance homocharge injection in the PE layer. The heterocharge in PE/EVA blends decreases as the VA content of blends increases, which was attributed by the enhancement of homocharge trapping at the interface and/or by the enhancement of negative charge injection via an increased electric field in the PE component
