Dielectric Properties of CCTO/Poly(vinylidene fluoride) Composites for Energy Storage Applications

摘要

A series of composites comprising of poly(vinylidene fluoride) (PVDF) as matrix and calcium copper titanate (CCTO) particles as fillers were prepared and-investigated. The dielectric displacement and energy density of the composites are enhanced and an energy density of 8.64 J/cm~3 has been obtained under an electric field of 310 MV/m with the CCTO concentration of 3 vol.%. The results indicate that the introduced low volume fraction of CCTO fillers contribute to the enhancement of the dielectric responses and energy storage properties of the composites.
