Multi-walled carbon nanotubes (MWCNTs) are characterized by using Transmission electron microscopy (TEM), and MWCNT-Silicone oil nanofluids are prepared by dispersing MWCNT in silicone oil using sonicator. The dependence of static dielectric constant (ε 0), excess dielectric constant (ε E ), ...
Fault information of machinery equipments is often contained in the process of lubricating oil wearing off.Meanwhile, the dielectric constant of the oil would changeaccordingly during the process. The principle of online oilcontamination monitoring based on dielectric constantmeasurement is proposed. The ...
It determines the lossiness of the medium. Similar to dielectric constant, low loss tangents result in a "fast" substrate while large loss tangents result in a "slow" substrate.Beware that the exact values can vary greatly depending on the particular manufacturer's process, so you should ...
PAESsshow good electrical properties and are thus used in electric and electronic applications, c.f.Table 7.3. They exhibit ahigh dielectric constantand a highdielectric strengthof15kVmm-1. The dielectricstrengthis a measure of a material’s ability to resist high voltage withoutdielectric breakdown...
Investigation of Thermal Conductivity of Alumina/silicone Oil Electrorheological Fluids Electrorheological (ER) fluids are new materials with good properties such as dielectric constant, dielectric loss or conductivity, which display remarkabl...

On the other hand, the dielectric constant of acrylic rubber and nitrile rubber is higher than that of silicone rubber. Thus, when acrylic rubber or the like is used for the material of the dielectric film, the electrostatic attraction with respect to the applied voltage increases, compared to...
where is the vacuum permittivity, is the dielectric constant of the polymer and z is the thickness of the elastomer film. Usually, strains of DEA are in the order of 10–35%, maximum values are up to 300%. Materials For the elastomer often silicones and acrylic elastomers are used. In ...
Silicone rubber (SR) composites exhibited significantly improved electromechanical properties via tuning the molecular flexibility by adding plasticizer. To decrease the enhanced elastic modulus of SR composites filled with high-dielectric-constant BaTiO3 (BT) particles, silicone oil (SO) plasticizer was...
Importantly, the breakdown strength was only slightly decreased by 10.4% following the addition of CEC and kept almost constant for CEC/PVCg elastomers with different loading concentrations of CEC (Fig. 3c and Supplementary Fig. 4). The detected breakdown strength of CEC/PVCg elastomers with 9...
A preferred suspending fluid has a low dielectric constant (about 2), high volume resistivity (about 10^15 ohm-cm), low viscosity (less than 5 cst), low toxicity and environmental impact, low water solubility (less than 10 ppm), high specific gravity (greater than 1.5), a high boiling ...
