POLARIZABLE NANOPARTICLES AND ELECTRORHEOLOGICAL FLUID COMPRISING SAME

摘要

An electrorheological fluid comprises a nanoparticle composition comprising a nanoparticle, uncoated or coated with a polymeric or metallic coating and covalently bonded to or coated on a surface of a polymeric or inorganic particle; and a dielectric fluid having a dielectric constant lower than that of the nanoparticle composition. A nanoparticle composition also comprises a carbon-based nanoparticle, covalently bonded to or coated on a surface of a conjugated polymer particle or inorganic particle, wherein the nanoparticle composition is a dielectric material.
