Significant Improvements in Dielectric Constant and Energy Density of Ferroelectric Polymer Nanocomposites Enabled by Ultralow Contents of Nanofillers

Advances in Materials, 2021
Polymer dielectrics with excellent processability and high breakdown strength (Eb) enable the development of high‐energy‐density capacitors. Although the improvement of dielectric constant (K) of polymer dielectric has been realized by adding high‐K ...

An Atomic Insight into the Chemical Origin and Variation of Dielectric Constant in Liquid Electrolytes.

Angewandte Chemie, 2021
Dielectric constant is a crucial physicochemical property of liquids in tuning solute-solvent interactions and solvation microstructures. Herein the dielectric constant variation of liquid electrolytes regarding to temperatures and electrolyte ...

Dielectric Constant of PbTe

Japanese Journal of Applied Physics, 1962
The low frequency dielectric constant of PbTe was determined by measuring the barrier capacitances of PbTe abrupt junctions at about 100 kc/s and low temperatures. The junctions were made by alloying In to p-type base crystals or Ag-Te alloy to n-type crystals.

Phthalocyanine with a giant dielectric constant

Dalton Transactions, 2012
Compound 1 has been prepared by the reaction of 4-nitrophthalonitrile and trans-2-methoxy-4-(2-nitrovinil)phenol by the common method of nucleophilic substitution of an activated nitro group in an aromatic ring. The metallophthalocyanines 2, 3 were prepared by the reaction of a dinitrile derivative with Co(OAc)(2) or Zn(OAc)(2) in DMSO.

Dielectric constant of ice

The Journal of Chemical Physics, 1974
A series expansion for the dielectric constant of the Bernal-Fowler-Pauling model of ice relaxed to allow Bjerrum faults is developed using a renormalization technique which eliminates large numbers of subgraphs. In the no fault limit the dielectric constant has the form ε0 = ε∞ + (4πG/3)(N/V)(μ2/kT) where the Bethe type approximation yields G = 3 and ...

Dielectric constant of cotton

Journal of Electrostatics, 1982
Abstract A technology derived from the technique for measuring magnetic susceptibility is applied to determine the average dielectric constant of cotton fibers. To a large extent the dielectric constant measurements are independent of the packing fraction and are reasonably independent of the shape of the sample.

Dielectric Constant of a Superconductor

Physical Review, 1963
The longitudinal dielectric constant is calculated for the extended Bardeen-Cooper-Schrieffer model of a superconductor. An explicit formula is obtained, which can be evaluated numerically. The competition between collective and single-particle effects is pronounced, so that the dielectric finction differs remarkably from the most elementary ...

The dielectric constant of zirconia

British Journal of Applied Physics, 1967
The dielectric constant of zirconia has usually been estimated from data on films. This has led to some values in the region of 12 and some in the region of 25. Since the true value is critical in the interpretation of thin-film behaviour, it has now been determined for the first time on single-crystal material.
