摘要: Abstract Recent studies have shown that giant flexoelectricity may exist in certain elastomers with bent-core molecular structures, which contradicts the previous theoretical estimation flexoelectric coupling is small those materials. In this Letter, we report an analogous phenomenon, i.e., direct effect, observed a polyvinylidene fluoride (PVDF) film. Our experimental indicate such enhanced effect might be induced by interaction between energy couplings of apolar and polar structures polymer film under elastic deformation.
