“…This was resulted from macroscopical heterogeneous interface of the different diphase structures [1]. On the other hand, the high-frequency dielectric response is a Debye relaxation behavior derived from the C-F dipole orientation polarization of PVDF matrix [25]. Interestingly, at 1 kHz, the nanocomposite with f NCB-NPs = 0.5 can exhibit good dielectric properties with high e 0 of about 210.8 and low tand & 0.83.…”

“…The common ceramic fillers used are BaTiO 3 [5,13,[15][16][17], (Ba 0.6 Sr 0.4 )TiO 3 [18][19][20], CaCu 3 Ti 4 O 12 (CCTO) [21][22][23], Na 0. 5 Bi 0.5 Cu 3 Ti 4 O 12 [24], and Ba(Fe 0.5 Nb 0.5 )O 3 [25]. Although significant efforts have been made for increasing e 0 of these ceramic/polymer composite systems, e 0 values these composites are difficult to significantly enhance by more than 100, in which 50 vol% ceramic particles was filled in.…”

Greatly enhanced dielectric permittivity (e 0 ) in poly(vinylidene fluoride) (PVDF) polymeric composites was induced by incorporating Na 1/3 Ca 1/3 Bi 1/3 Cu 3 Ti 4 O 12 (NCB) nanoparticles. The NCB/PVDF composites were fabricated by conventional mixed powders and hot pressing. Nanosized (NCB-NPs) and microsized-powders (NCB-MPs) prepared, respectively, by chemical combustion and solid state reaction methods were used as fillers. The dispersion of NCB-NPs was quite good in the PVDF matric. A greatly improved e 0 of PVDF-based polymeric composites can be induced by filling with NCB-NPs compared to that of the NCB-MPs/PVDF composite. Interestingly, at 10 3 Hz, the nanocomposite with 50 vol% of NCB-NPs can exhibit good dielectric properties with high e 0 of about 210.8 and low loss tangent (tand & 0.83). This enhanced e 0 value is much larger than that of PVDF polymer by a factor of &20. The increase in e 0 in the nanocomposites is attributed to large interfacial areas and very short interparticle distance. These can cause a great increase in the interfacial polarization intensity.

“…Ferroelectric polyvinylidenfluorid (PVDF) [7,8], its copolymer with hexafluoropropylene [9], as well as nonferroelectric substances such as polyimide [10], polyurethane [11], polytetrafluoroethylene [12], polyvinyl chloride [13], polybenzoxazol [14] and epoxy polymers [15,16,17] are most often used as a matrix in composite systems. Nanodisperse BaTiO 3 [7,8,9,17,18], Pb(Zr,Ti)O 3 (PZT) [14,15,19] and Ba(Fe 0.5 Nb 0.5 )O 3 [20,21] are most often used as a ferroelectric filler.…”

The high dielectric constant ferroelectric-polymer nanocomposite was developed for producing the heat-resistant and chemical stable planar layers. According to the composite coatings formation conditions, the following value ranges of dielectric constant and loss factor were received: 30–400 for dielectric constant and 0.04–0.1 for loss tangent, accordingly. Unlike of composite components, the obtained composite material is characterized by thermo-stability of electrical parameters up to 250 °C. The dielectric frequency spectra of the composite exhibit two clearly visible peaks in contrast to the spectra of the polymer and ferroelectric ceramics. The developed composite material can be used as a built-in film capacitors material in microelectronic devices.
