Pressure induced piezoelectric ß-phase crystallization in screen printed polymer thick films

Abstract

In this work, a novel method of producing thick film piezoelectric polymer film has been used based on the use of pressure during crystallisation. This method induces the desired piezoelectric p - phase in Polyvinylidene Fluoride (PVDF). The screen printing technique was used to fabricate the films on 96% alumina substrates. Various characteristics have been studied, including the thermal and structural properties of the polymeric films.
