Abstract

We have developed a new driving mechanism to induce deformation and movement of a neutral polymer gels in non- conducting medium. The main idea was to incorporate such finely distributed colloidal particles into a swollen network, which response to electric field. Since the particles can not leave the gel matrix, so that all of the forces acting on the particles are transmitted directly to the polymer chains result in either locomotion or deformation of the gel. Bending of weakly cross-linked poly(dimethylsiloxane) gels containing finally distributed electric field sensitive particles has been studied in silicon oil. Under an external electric field these gels underwent significant and quick bending. Scaling down the geometry may provide a new principle to build soft microelectromechanical actuators.
