Abstract

The behavior of electrically charged polypropylene foam under heating and UV irradiation was studied using dielectric resonance spectroscopy. UV irradiation below 210 nm leads to detrapping of charges and a reduced d 33 coefficient. The samples retained their quasipiezoelectric properties during short-time heating up to 80 °C. However, the large temperature drift of d 33 usually requires operating these materials in a temperature-controlled environment.
