For example, pure ice has a dielectric constant of 3.2 and loss factor of 0.003 at 0 °C while liquid water at the same temperature has an ε′ of 79 and an ε″ of 21. As can be seen in Figs. 1 and 2, the higher the moisture content, the more dramatic the change in ...

4 we plotted the dielectric constant of polymers calculated by Sharma et al.9. Both figures demonstrate the inverse dependence of the dielectrqic fficffiffioffiffiffinffiffistant with the band gap. In fact, the trend is more pronounced for the refractive index since n ¼ ε1poly and hence...
the former is the maximum voltage that can be applied to a material before it loses its insulating properties, and the dielectric constant is the capacity of a material to store electrical energy. These values are also expressed differently. Dielectric constant is a ratio with no units of measur...
For unoriented polymers the bounds are considerably tighter than the Hashin鈥揝htrikman bounds, the latter being the best possible without knowledge of phase geometries. The bounds presented here are sufficiently tight to represent the dielectric constant with practical accuracy for a number of ...
Ultra-high dielectric constant values can be achieved; however, a high conductivity and dielectric loss also result when the filler content approaches the percolation threshold. To overcome these limitations, researchers have focused on improving the dielectric properties of the mate- rials via ...
The present invention is drawn toward latex particulates having a bulk density from 0.90 g/cm3 to 1.10 g/cm3 and a surface dielectric constant from 2.0 to 3.0. These latex particulates can be used in ink-jet inks, providing the advantages related to the use of latex while exhibiting good fr...
The latter is expressed by a number called the dielectric constant. A common, yet notable example of a dielectric is the electrically insulating material between the metallic plates of a capacitor. The polarization of the dielectric by the applied electric field increases the capacitor's surface ...
