Dielectric and Pyroelectric Properties of Ferroelectric SBN–PVDF Composites Prepared by Hot‐Uniaxial Press

Composites of polyvinyledene fluoride ( PVDF ) and strontium barium niobate ( Sr _x Ba _{1− x} Nb ₂ O ₆ for x = 0.53/ SBN )/Ф SBN − (1 − Ф) PVDF with Ф = 0.1 to 0.3 have been prepared by hot uniaxial press. Structural, morphological, dielectric and pyrolectric properties of the composites have been studied. Self‐sustaining thick films with a 0–3 connectivity have been synthesized. The dielectric constant (ε _r ) was found to increase with the increase in ceramic volume fraction (Ф) in the composite. The composite with Ф = 0.3 is found to have highest values of pyroelectric coefficient (p _i ) ~13.475 μC/m ² K, FOM _I ~0.481 μC/m ² K and FOM _II ~20.13 μC/m ² K with good mechanical flexibility.
