Abstract

Dielectric electroactive polymers respond to an applied electric field by deformation as described by the Maxwell effect. The response depends on the polymers' dielectric constant and stiffness. Addition of a high dielectric filler material has been shown to enhance the strain response. We report preliminary results on the enhancement of p(EGPEA) polymer films by addition of 1 w/v% of gold-capped, 500 nm SiO₂ Janus particles (JP-SiO₂). In comparison to pure p(EGPEA) and p(EGPEA) filled with unmodified SiO₂ particles, JP-SiO₂ p(EGPEA) films show an up to 24 times enhanced response. Measurement of the relative dielectric constant and the Young's Modulus indicate that the Janus particle additive increases the relative dielectric constant of the films, while at the same time decreasing the Young's Modulus leading to an overall larger electrostrictive coefficient for the JP-SiO₂ p(EGPEA) films.
