The static and the real and imaginary components of the dynamic pyroelectric coefficients were measured on a film of polyvinylidene fluoride (PVF/sub 2/) over a 90--370 K temperature range. These are the first pyroelectric coefficients of PVF/sub 2/ measured at extremely low temperatures, and the first complex dynamic pyroelectric coefficients reported in the literature. The static coefficient was small and constant below the glass transition temperature T/sub g/, but increased very rapidly above T/sub g/. The real dynamic coefficient was in good qualitative agreement with the static value. The imaginary dynamic coefficient had a complicated frequency dependence which can be used to examine elastic and piezoelectric relaxation processes.
