| ABSTRACT |
|
In Pb1-xLax(Zry, Tiz)1-x/4O3 system, it selects the composition 7/65/35 (x=7, y=65, z=35) that was reported to have eminent Pyroelectric properties, and that is sintered with PbZrO3＋0.3wt.% PbO2 atmosphere powder. From the sintered ceramic and Poly Vinyl Alcohol, the thin wafers are fabricated with 0-3connectivity, and they are researched in Pyroelectric properties and the others according to volume ratio between ceramic and polymer. It was possible to fabricate the film containing ceramic up to 80vol% in PVA polymer. The increment of PLZT ceramic volume fraction improve the pyroelectric coefficient of the composite. On Pyroelectric coefficient and the figure of merit, a little inflection caused by glass point(Tg) of PVA appeared. The degree of inflection is proportioned to the amount of PVA. |
