โœฆ Synopsis

Hysteresis phenomena in BaTiO3: PVDF composites with different weight fractions of BaTiOa and PVDF were studied in the temperature range 20-180~ A sinusoidal electric field of up to 100 kVpm -1 at 50 Hz was used. The saturation polarization, Psat, remanant polarization, Pr, and coercive field, E c, were observed to increase with increasing ceramic content of the composite samples. An increase of polarization with temperature was observed for all composites up to 80~ This has been explained on the basis of an increase in the conductivity of the PVDF phase.

Thin films of the composites formed between poty(vinylidene fluoride) (PVDF) and lead zirconium titanate (PZT) and also barium titanate with 0-3 connectivity, have been obtained by dispersion of the ceramic powder in a solution of PVDF in dimethylacetamide DMA. Evaporation of the solvent at 65 ~ all
