Dielectric and pyroelectric properties of the composites of ferroelectric ceramic and poly(vinyl chloride)
The dielectric and pyroelectric properties of lead zirconate titanate/poly(vinyl chloride) [PZT/PVC] and barium titanate/poly(vinyl chloride) [BaTiO₃/ PVC] composites were studied. Flexible composites were fabricated in the thin films form (200−400 µm) by hot-pressed method. Powders of PZT or Ba...

Порошки PZT та BaTiO₃ у вигляді керамічних частинок з діаметром меншим за 0.75 мкм розпилено в матриці полівінилхлориду, при чому утворилися композити зі зв’язністю 0−3. Розподіл керамічних частинок у полімерній фазі досліджено за допомогою електронного скануючого мікроскопа. Також проведено аналіз термічно стимульованих струмів.

| description |
The dielectric and pyroelectric properties of lead zirconate titanate/poly(vinyl
chloride) [PZT/PVC] and barium titanate/poly(vinyl chloride) [BaTiO₃/
PVC] composites were studied. Flexible composites were fabricated in the
thin films form (200−400 µm) by hot-pressed method. Powders of PZT or
BaTiO₃ in the shape of 6 75 µm ceramics particles were dispersed in a
PVC matrix, providing composites with 0−3 connectivity. Distribution of the
ceramic particles in the polymer phase was examined by scanning electron
microscopy. The analysis of the thermally stimulated currents (TSC)
have also been done. The changes of dielectric and pyroelectric data on
composites with different contents of ceramics up to 40% volume were investigated.
The dielectric constants were measured in the frequency range
from 600 Hz to 6 MHz at room temperature. The pyroelectric coefficient for
BaTiO₃/PVC composite at 343 K is about 35 µC/m²K which is higher than
that of β-PVDF (10 µC/m²K). |
