“…Most of dielectrics used as fillers in the development of polymer based 0-3 composites are inorganic polar materials, especially ferroelectrics [3][4][5][6][7][8][9], such as BaTiO 3 (BT), (Ba,Sr)TiO 3 (BST), Pb(Mg 2/3 Nb 1/3 )O 3 (PMN), P(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) and Pb(Zr,  Ti)O 3 (PZT), since these dielectrics exhibit a dielectric constant as high as 10 3 to 10 4 [10].

Dielectric composites with a high and temperature-independent dielectric constant

Dielectric composites made using P(VDF-CTFE) 88/12 mol% as polymer matrix and both micro-sized and nano-sized CaCu 3 Ti 4 O 12 (CCTO) particles as filler are developed. These composites exhibit high dielectric constant with a small dielectric loss. More importantly, it is found that the dielectric constant of these composites is almost independent of temperature from 25 ℃ to 125 ℃. Comparing the composites made using micro-sized CCTO particles, the composites made using nano-sized CCTO particles exhibit a smaller dielectric loss. The dielectric properties of these composites indicate that the nano-sized CCTO particles have a smaller dielectric constant than the micro-sized CCTO particles.

“…The printed composite showed higher relative permittivity than has been previously reported with the same loading level, while the dielectric losses remain at the same level [8][9][10][11][12][13][14][15]. This is almost certainly due to the selection of the matrix material and the particle size, and the new fabrication technique including chemical solution processing with specific surfactant and printing which enabled a low agglomeration level and a more uniform distribution of the filler.…”

“…BT (Sachtleben, Germany) with an average particle size of 0.2 μm was used as the ceramic filler. The use of particles with 0.2 -0.3 μm size has been reported to ensure a high permittivity in BT -PVDF composites [13]. The BT particles were coated with a surfactant, Malialim® AAB-0851 (NOF Co., Japan).…”

In this research a composite for printable capacitors using screen printed structures and low temperature curing ferroelectric ink was investigated. The realized ink consisted of 40 vol-% barium titanate in a poly(vinylidenefluoride-trifluoroethylene) matrix. DuPont silver ink 5064H was used for the conductive lines in the design and the maximum process temperature was 130 °C. The thickness of the composite and the area of the printed capacitor were 43 μm and area 25 mm 2 , respectively. The obtained relative permittivity of the composite was 46 and the tan δ was 0.15 at 1 MHz. Additionally, the microstructure of the composite was investigated and the temperature dependence of the dielectric properties measured. The capacitance of the parallel plate structure was approximately 200 pF at 1 MHz. This is easily adjustable by changing the printing pattern, number of layers or the filler loading. The freedom of choice in integration and capacitance value selection makes the ink highly usable in, for example, decoupling capacitors that are compatible with inorganic, organic and even flexible, substrates.

“…Therefore, many ferroelectric and relaxor ferroelectrics, such as BaTiO 3 (BT), Pb(Mg 1∕3 Nb 2∕3 )O 3 (PMN), Pb(Zr,Ti)O 3 (PZT), (Ba,Sr)TiO 3 (BST), have been widely used in the development of DDCs. [16][17][18][19][20][21][22][23][24][25] Unfortunately, the dielectric constant of a ferroelectric or relaxor ferroelectric is strongly dependent on the temperature. 26 The discovery of CaCu 3 Ti 4 O 12 (CCTO) provides new opportunities/avenues to develop high performance composites due to the facts that CCTO exhibits a very high dielectric constant (> 10 4 ) that is also weakly dependent on the temperature.…”

Physical aspects of 0-3 dielectric composites

0-3 dielectric composites with high dielectric constants have received great interest for various technological applications. Great achievements have been made in the development of high performance of 0-3 composites, which can be classified into dielectricdielectric (DDCs) and conductor-dielectric composites (CDCs). However, predicting the dielectric properties of a composite is still a challenging problem of both theoretical and practical importance. Here, the physical aspects of 0-3 dielectric composites are reviewed. The limitation of current understanding and new developments in the physics of dielectric properties for dielectric composites are discussed. It is indicated that the current models cannot explain well the physical aspects for the dielectric properties of 0-3 dielectric composites. For the CDCs, experimental results show that there is a need to find new equations/models to predict the percolative behavior incorporating more parameters to describe the behavior of these materials. For the DDCs, it is indicated that the dielectric loss of each constituent has to be considered, and that it plays a critical role in the determination of the dielectric response of these types of composites. The differences in the loss of the constituents can result in a higher dielectric constant than both of the constituents combined, which breaks the Wiener limits.
