Abstract
The non-isothermal crystallization and Curie transition behavior of composites consisting of lead zirconale titanate (PZT) particles embedded in a vinylidene fluoride-trifluroethylene (P( VDF-TrFE)70/30) copolymer matrix were investigated using differential scanning calorimetry. The crystallization temperature, crystallization rate and crystallinity of the copolymer matrix was not affected significantly by the inclusion of the PZT particles, while the overall Curie transition enthalpy decreased with increasing the PZT content. The relative amount of enthalpy corresponding to the transition from the paraelectric high-temperature (HT) phase to the ferroelectric cooled (CL) phase also decreased with increasing the PZT content. This suggested that PZT particles might restrain the formation of gauche conformational defects in ferroelectric crystals and make ferroelectric crystals more perfect.
