This paper reports on the investigation into space charge characteristics at interfaces of multi-layer polymeric materials. Planar low density polyethylene (LDPE) samples were used in this study. DC voltage up-to 10 kV was applied to the sample and space charge measurements were taken using the pulsed electro-acoustic (PEA) technique. Experimental results indicated that the electrode interface plays an important role in determining the bulk charge formation and polymer layer interface has different effects on electrons and holes trapping.
