Abstract Ferroelectric polymers are one of the next- generation pulsed capacitor materials for the potential application in capacitive energy storage. This polymer with higher saturated polarization, smaller remnant polarization, and higher electrical breakdown are the most promising candidates. In this work, the dielectric properties and energy storage capacity of the bilayer polymer films of Poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP)) and polyurethane (PU) were studied. These bilayer polymers were prepared by layer- by- layer method at the condition of variable layer thickness. The results show that the dielectric constants and the saturated polarization of the bilayer films increased, and bilayer films with P70/PU30 exhibit electrical high breakdown strength up to 379 V/μm. Moreover, enhanced energy storage density and the energy efficiency of the bilayer constrictors will be discussed for the capacitive energy storage polymers.

Abstract (1-x)(0.96Na0.5Bi0.5TiO3-0.04BiMnO3)-xLaMnO3 ternary solid solution films were fabricated by Sol-gel methods. It takes advantage of the large polarization from 0.96NBT-0.04BMO limit solid solution at crucial point of solubility limit to enhance energy density. And LaMnO3 was introduced to improve the energy storage efficiency via the enhancement of relaxor behaviors. It is shown that the relaxor behaviors had been enhanced, and a large energy storage density of 87.9 J/cm3 and efficiency of 56.5 % were achieved for 0.85(NBT-BMO)-0.15LM films, with increase ratio of 4.9 % and 13.3 % respectively than 0.96NBT-0.04BMO solubility limit films. However, when LaMnO3 is beyond a certain limit, the breakdown strength is reduced due the formation of the current channel. Thus it suggests a alternative method that combining relaxor behaviors with solubility limit films, which provides a way to regulate the energy storage performances for film capacitors.
