Abstract :
Improvement of thermal stability of piezoelectricity is a key to wide application of polypropylene ferroelectrets as a sensor. For this purpose, direct fluorination using fluorine gas, as one of the most effective approaches to the chemical modification of polymers, was performed to cellular PP films.
