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.
