| 摘要 |
This invention is directed to a gel-like solid whose viscoelastic properties such as shear modulus and loss factor vary when the solid is exposed to an electric field. The material comprises polarizable particles dispersed in a lightly crosslinked polymer matrix. The non-conductive polymer matrix is the reaction product of liquid prepolymer such as crosslinkable polydimethylsiloxanes and curative therefor. The polarizable particles comprise high dielectric constant material such as zeolite or silicate.
