Ferroelectric ceramic particles based on lead titanate zirconate (PZT) were
dispersed in a polymer matrix based on easter oil. After the poll ng proce
ss, the pyroelectric activity of th is composite was measured using a direc
t method in which a linear heating rate was applied to the pre-poled sample
s. The pyroelectric coefficient at 343 K is comparable with that of a PZT-p
oly(vinylidene fluoride) (PVDF) composite and significantly higher than tha
t of PVDF. (C) 1998 Kluwer Academic Publishers.
