Dielectric and pyroelectric properties of triglycerol-gelatin films

The dielectric and pyroelectric properties of triglycerol-gelatin thick films were studied as a function of temperature and frequency. The films exhibited a strong dispersion in the dielectric permittivity accompanied by a high dielectric loss near room temperature. The pyroelectric current measured...

520 |a The dielectric and pyroelectric properties of triglycerol-gelatin thick films were studied as a function of temperature and frequency. The films exhibited a strong dispersion in the dielectric permittivity accompanied by a high dielectric loss near room temperature. The pyroelectric current measured by the static Byer-Roundy method is heavily dominated by the thermally stimulated currents. Measurements performed on prepoled samples using the dynamic technique of A.G. Chynoweth (1956) clearly proved the presence of a true, reversible pyroelectric response in the examined films. The value of the pyroelectric coefficient of the films was found to be comparable to that of polyvinylidene fluoride (PVDF)
