Dielectric constant of common materials Dry air has a low dielectric constant. It can undergodielectric breakdown, a condition in which the dielectric suddenly begins to conduct electrical current. However, the breakdown is not permanent because when the excessive electric field is removed, air will ...
This chapter presents a list of dielectric constants of different materials in alphabetical order.doi:10.1016/B978-012763560-6/50029-5J WORKMANJRWorkman, J.J. (2001). 26 - Dielectric constants of materials (in alphabetical order). In J. Workman (Ed.), The handbook of organic compounds. ...
principalaxisof thecrystal. Because the value of the dielectric constant for air is nearly the same as that for avacuum, for all practical purposes air does not increase the capacitance of a capacitor. Dielectric constants ofliquidsandsolidsmay be determined by comparing the value of the ...
ε0 = permittivity of vacuum or free space (8.854187817 10-12 C2 /(N m2 )) Relative permittivity - εr - and permittivity - ε - for some substances. Note that permittivity may change with temperature for most materials. Relative Permittivity Constants Product Relative Permittivity - εr -...
function of temperature at a constant pressure (Akizuki et al., 2014). As depicted in this figure, the dielectric constant of water decreases sharply with the increase of water temperature. The dielectric constants of water at temperatures of 280 and 300°C with pressure of 25MPa are similar ...
Dielectric constants and losses of 13 pharmaceutical materials were measured over a frequency range of 1MHz1GHz at 23±1°C using a parallel-electrode measurement system. Effects of field frequency, material density and moisture content on dielectric properties were studied. Material dielectric ...
Dielectric materials having modified dielectric constants and methods for modifying the dielectric constant of a dielectric material are provided. Generally, the dielectric constant of a dielectric material is modified by providing relieved portions within the dielectric material. The relieved portions may ...
High-performance polymer materials with low dielectric constant and low dielectric loss have been widely used in high-speed communication network. This review briefly introduces several common polymer materials, including polyimides, poly (benzoxazole)s, poly (aryl ether)s, poly (tetrafluoroethylene), ...
where XYZ0 is the value of the considered property for the inert solvent without solvation abilities, and s, a, and b are constants that represent the sensibility (dependence) of the solvent parameters [104]. It has been used to describe reactions rates and equilibrium constants, e.g. Bulgar...
to a user. However, conventional methods for increasing values of dielectric constants of elastomeric materials makes the elastomeric materials less flexible, impairing use of the elastomeric materials with higher values of dielectric constant values in applications where flexibility is beneficial....
