Abstract :
So far, linear polypropylene (PP) foam is the most extensively investigated ferroelectret. In the present studies, cross-linked PP (XPP) foam sheets are modified by a hot-press process, and then corona charged to be piezoelectric. Thereafter their piezoelectric activities are investigated.
