Abstract
Polyvinylidene fluoride (PVDF) and barium titanate were mixed in different weight fractions, and the infrared spectra of PVDF (pure) and various proportions of composite were studied. The absorption peak amplitudes corresponding to the a form of PVDF have been significantly reduced, absorption peak amplitudes corresponding to the ß form of PVDF have been slightly affected, and the absorption peak amplitudes corresponding to the β form of PVDF have been considerably increased. The composite with 70% wt. of BaTiO3 has a high dielectric permittivity and pyroelectric coefficient.Keywords
