The dielectric constant ε can be calculated on the basis of the general equation for parallel plate configurationε=Ct/8.85×10−12Awhere C is the measured capacitance value in Farad, t the thickness of the film in meters, A is the cross-sectional area in square meters. The loss factor ...
The dielectric findings showed that a blend containing 40% of CA by weight had a dielectric constant of 2.9 and an electrical conductivity of 1.26 x 10-11 S cm-1 at 100 Hz and 20 degrees C while exhibiting better mechanical rigidity in the rubbery state than neat PLA. In...
The dielectric constant of ionic solutions is known to reduce with increasing ionic concentrations. However, the origin of this effect has not been thoroughly explored. In this paper we study two such possible sources: long-range Coulombic correlations and solvent excluded-volume. Correlations origina...
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 Figures 1 and 2, the higher the moisture content, more dramatic the change in dielectric ...
The results demonstrate a three-fold improvement in the dielectric constant of 40 wt.% BaTiO3 and graphene-TPU-PLA blends composites relative to that of the neat TPU, along with an improved tensile strength. The tensile strength improvement is attributed to the support of the TPU matrix against...
The maximum dielectric constant was increased up to 2500 for the sample with x = 0.01. A high dielectric breakdown strength of 239 kV cm−1 was obtained at x = 0.01. The high grain boundary resistance resulted from a charge compensation by Dy doping benefits the improved diele...

where ε′ is a constant of proportionality defined as the relative permittivity (dielectric constant) of the material between the electrodes, ε0 is a constant known as the permittivity of free space (1/3671×10−9 Farads m−1), A is the area of the electrodes (m2), and d is the...
