Abstract
The time resolved fast pulsed electro-acoustic (PEA) method is used to investigate the space charge characteristics in an additive-free poly(propylene-ethylene) (PPE) copolymer in film form. The 190 mum-thick films were submitted to DC and low frequency AC stress for various durations at various temperatures. Upper electrode (UE) and lower electrodes (LE) are semi-conductive polyethylene and aluminum, respectively.
