Abstract
The ferroelectric polymer have been largely studied due to their high field-induced strain. This specific characteristic is essentially required in a range of applications such as actuators and sensor. The ferroelectric PVDF-co-TrFE(65/35)- P3HT conductive polymer blend composite have been produced by precipitation and subsequent hot press processing. Au electodes evaporated on both side of the composite films. Transvers strains in these blend film were investigated by two lasers measurement system. The P(VDF-TrFE)/conductive polymer composite with high content wt% conductive polymer loading had much higher electromechanical strain, dielectric constant than the P(VDF-TrFE) neat film and low content wt% composites.
