“…This dielectric constant is much higher than that of other ceramic-polymer composites. Subsequently, a great deal of research has occurred regarding the development of polymer-based composites using CCTO as filler [16][17][18][19][20][21][22][23][24]. From an application point of view, thin film of a dielectric composite is highly desirable.…”

“…In order to reach a consistent uniformity in a thin composite film, the size of the filler particles should be small. Nanosized CCTO particles have been used in the development of polymerbased composites [18,[21][22][23][24]. In those studies, the nanosized CCTO particles were prepared using different methods including wet chemical route [24].…”

Composite thin film is highly desirable for the dielectric applications. In order to develop composite thin film, a nanocomposite, in which nanosized CaCu 3 Ti 4 O 12 (CCTO) particles are used as filler and P(VDF-TrFE) 55/45 mol% copolymer is used as polymer matrix, is investigated. The contents of CCTO in the nanocomposites range from 0% to 50 vol%. The dielectric property of these nanocomposites was characterized at frequencies ranging from 100 Hz to 1 MHz and at temperatures ranging from 200 K to 370 K. A dielectric constant of 62 with a loss of 0.05 was obtained in nanocomposite with 50 vol% CCTO at room temperature at 1 kHz. At the phase transition temperature (∼340 K) of the copolymer, a dielectric constant of 150 with a loss less than 0.1 was obtained in this nanocomposite. It is found that the dielectric loss of the nanocomposites is dominated by the polymer which has a relaxation process. Comparing to composites made using microsized CCTO, the nanocomposites exhibit a much lower dielectric loss and a lower dielectric constant. This indicates that the nanosized CCTO particles have a lower dielectric constant than the microsized CCTO particles.

“…Compared to inorganic dielectric materials (i. e., ferroelectric ceramics) [246][247][248][249], polymer-based dielectric materials have received tremendous attentions because of their excellent mechanical properties, high electric breakdown field and ease of synthesis [250][251][252][253][254]. NCPs as a new class of conducting organic materials provided a unique opportunity as conducting fillers in polymer-based dielectric composites [255][256][257][258][259][260][261][262][263].…”

“…[27][28][29] Composites using CCTO have been widely studied. [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] It should be mentioned that, in most of DDCs using nanosized ceramic fillers, the dielectric constant can only reach the value around 50 even for the composites with a volume fraction of filler up to 50 vol.%. 7 It is well known that the high filler content reduces the composite flexibility and results in weak mechanical properties, which can limit its applications.…”

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.
