Title of Paper:
Electric energy storage properties of poly(vinylidene fluoride)
Summary:
High discharged energy density observed in polyvinylidene fluoride PVDF based copolymers
has attracted considerable research interests in the past years. Crystalline properties exhibit great
influence on their dielectric and energy storage properties. To understand how crystalline properties
influence the energy storage properties of PVDF, PVDF films with three different crystal forms are
investigated in this paper. It is shown that -PVDF is allowed to work under higher electric fields
than - and -PVDF in the absence of phase transition in -PVDF and early polarization saturation
in -PVDF. Consequently, -PVDF exhibits the highest energy density of 14 J /cm3 under 500
MV/m electric field.
