This review summarizes our work at the University of Bayreuth over the last few years on improving the electret performance of the commodity polymer isotactic polypropylene (Sect. 3) and the commodity polymer blend system polystyrene/polyphenylene ether (Sect. 4) to provide electret materials based on inexpensive and easily processable polymers. To open up polymer materials for electret applications at elevated temperatures we concentrated our research on commercially available high performance thermoplastic polyetherimide resins and synthesized several fluorinaled polyetherimides to identify structure-property relations and to improve further the performance at elevated temperatures (Sect. 5). [Pg.164]

To study cooling rate effects which might affect the supramolecular self-assembly of trisamides in i-PP, we investigated the influence of the processing conditions on the electret performance. Isotactic polypropylene containing 0.09 wt% of compound 1 was chosen for these experiments. After compression molding, the films... [Pg.173]

Recently, electrets made with cellular stmctured polymers have received attention as new piezoelectric materials with a high piezoelectric 33 coefficient exceeding 100 pC/N. In particular, research on cellular polypropylene (PP) film has been conducted to improve both its physical characteristics and its applications (Neugschwandtner et al. 2000 Hillenbrand and Sessler 2000 Paajanen et al. 1998, 2001 Zhang et al. 2007). [Pg.633]
