Inversely polarised ferroelectric polymer contact electrodes for triboelectric-like generators from identical materials

Abstract

Although it is known that triboelectric nanogenerators (TENG) based on ferroelectric polymer films show better performance, the origin of this enhancement remains poorly understood. To date, it has been accepted that enhancement is observed to due shift of the “effective work function” of ferroelectric polymer insulator which in turn enhance electron transfer between TENG electrodes. The present study reveals that this view is incorrect and, in reality, the enhancement is observed due to induction driven by piezoelectric charges. Furthermore a novel piezoelectric-electrostatic generator (PEEG) has been constructed from inversely polarised polyvinylidene films, which exhibit higher performance than TENG for mechanical energy conversion to electricity.
