One‐dimensional relaxor ferroelectric nanofiller can enhance the dielectric properties of polyvinylidene fluoride (PVDF)‐based composite films. However, the impact of fiber morphology on these properties is unclear, with existing studies lacking systematic investigation. In this work, BaZr 0.2 Ti 0.8 O 3 nano...
