Kurzbeschreibung (Abstract)
A study on the influence of the crystal mod- ification ( ␣ and  ) of isotactic polypropylene (i-PP) films on the resulting electret properties is presented. Two commer- cial nucleating agents, sodium 2,2⬘-methylene-bis(4,6-di-tert- butylphenyl)-phosphate (NA11) and N,N⬘-dicyclo-hexyl- 2,6-naphthalene-dicarbox-amide (NU100), were employed in this investigation. Isothermal charge decay was measured at 90°C. In hot pressed isotropic polypropylene films, no significant differences in the charge storage properties were observed for ␣ - and  -nucleated specimens. In addition, the article presents the influence of the nucleating agents at different concentrations on the PP-film morphology of bi- axially stretched films with respect to electret features. It was possible to prepare elongated cavities with the virtually insoluble NA11 additive during stretching, even at concen- trations below 0.3 wt %. These films displayed slightly im- proved electret properties in comparison to stretched neat PP films due to generated cavities acting as barriers for the drift of charges. Various draw ratios were also studied for i-PP films with 0.15 wt % NA11.
