| Popis: | The great influence of O 2 on the electrical aging of polypropylene films. The lifetime of the capacitor model with 2x13.6 μm-thick PP films is about 25 h with O 2 saturated liquid and more than 1500 h without O 2 . Two different degradation are obtained on a given film and good agreement is shown between electrical (breakdown voltage) and physicochemical measurements (FTIR spectroscopy) |
