In this letter, the dielectric properties of the untreated multiwall carbon-nanotubes/poly(vinylidene fluoride) (MWNT/PVDF) composites are studied. Towards low frequencies, the dielectric constant of a composite with about 2.0 vol % of MWNT increases rapidly and the value of the dielectric constant...
The application of silicone rubber as dielectric elastomer sensor is limited by its poor strain sensing performance because of low dielectric constant (e '). In this study, we designed and fabricated a fluorosilicone dielectric composite with high e ' and capacitive strain sensing performance by desi...
The silicone/TiO2 composite films exhibited, in comparison with pure silicone, a steadily improvement of dielectric constant and elastic modulus with the augment of TiO2 particles. A transverse planar strain of 18% with pre-strain of 5% at 50V/μm was obtained, which was 50% higher than the ...
