ABSTRACTDielectric polymers with high energy density with low loss at high electric fields are highly desired for many energy storage and regulation applications. A polar-fluoropolymer blend consisting of a high energy density polar-fluoropolymer of poly(vinylidene fluoride-chlorotrifluoroethylene) (P(VDF-CTFE)) with a low dielectric loss polymer of poly(ethylene-chlorotrifluoroethylene) (ECTFE) was developed and investigated. We show that the two polymers are partially miscible which leads to blends with high energy density and low loss. Moreover, by introducing crosslinking to further tailor the nano-structures of the blends a markedly reduction of losses in the blend films at high field can be achieved. The crosslinked blend films show a dielectric constant of 7 with a dielectric loss of 1% at low field. Furthermore, the blends maintain a high energy density and low loss (∼3%) at high electric fields (> 250 MV/m).

ABSTRACTDielectric capacitors for energy storage are of great importance in modern electronics and electric systems. It is a challenge to realize the high energy density while maintain the low dielectric loss. We investigated an ultra high breakdown electric field of 1.1 GV/m, which is approaching the intrinsic breakdown, in aromatic polythiourea, a new dielectric material that serves a high energy density of 23 J/cm3 as well as high charge-discharge efficiency above 90%. The molecular structure and film surface morphology were also studied, it was proved a polar amorphous phase and glass state material could significantly suppress the high field conduction to several orders smaller compared with regular polymer dielectric materials, which are usually semi-crystalline and in rubber phase.

(1-x) BaTiO 3-x Bi ( Mg 1/2 Ti 1/2) O 3 (BT-BMT, 0.3 ≤ x ≤ 0.6) ceramics were prepared by the conventional mixed oxide method. Dielectric measurements showed highly diffusive and dispersive relaxor-like characteristics for all compositions. For 0.3 ≤ x ≤ 0.4, all these compositions possess a stable dielectric permittivity of approximately 1500 and low loss tangent (tan δ < 2%) in the temperature range 200–400°C, which may have great potential for high-temperature applications. For all samples, examination of the polarization hysteresis behavior shows an obvious linear hysteresis loops at 120°C. It was found that the energy density of about 0.7 J/cm3 could be achieved at 120°C for x = 0.4 sample, indicating a high energy density.
