Abstract:
1. An electroactive sensing/actuating material comprising a composite of (i) a polymer with polarizable moieties, (ii) an effective amount of carbon nanotubes in said polymer for a predetermined electromechanical operation of said composite when said composite is affected by an external stimulus, and (iii) micro to nano-sized particles of an electroactive ceramic in said polymer wherein a ratio of dielectric constant of said ceramic to dielectric constant of said polymer is at least 50:1, and wherein said nanotubes are incorporated in said polymer in an effective amount that provides a dielectric constant for said composite that is greater than said dielectric constant of said polymer while simultaneously providing for said predetermined electromechanical operation of said composite.
