Silicone elastomers with high dielectric permittivity and high dielectric breakdown strength based on tunable functionalized copolymers [PDF]

, 2015
High driving voltages currently limit the commercial potential of dielectric elastomers (DEs). One method used to lower driving voltage is to increase dielectric permittivity of the elastomer.

The effect of multilayered film structure on the dielectric properties of composites films based on P(VDF-HFP)/Ni(OH)2

Nanocomposites, 2019
High dielectric constant ceramics fillers are widely used as fillers in polymer matrix to prepare high performance dielectric composites. Homogeneous filler distribution in these composites films is found to be quite difficult to achieve balance between ...

Influence of Ester Liquids on Dielectric Strength of Cellulose Kraft Paper

Energies, 2022
Generally, impregnation of solid insulation is performed to increase the dielectric strength and reduce the dielectric losses of solid insulants. This increase in dielectric strength depends on the oil’s diffusion and dielectric properties.

Stretch dependence of the electrical breakdown strength and dielectric constant of dielectric elastomers

Smart Materials and Structures, 2013
Dielectric elastomers are used for electromechanical energy conversion in actuators and in harvesting mechanical energy from renewable sources. The electrical breakdown strength determines the limit of a dielectric elastomer for its use in actuators and energy harvesters.

Dielectric Breakdown of a Mott Insulator

, 2012
We study the nonequilibrium steady state of a Mott insulator coupled to a thermostat and driven by a constant electric field, starting from weak fields, until the dielectric breakdown, and beyond.
