Abstract
Two pyrite powder sorts were physically incorporated in a silicone rubber matrix consisting of high molecular mass (Mv=450000) polydimethylsiloxane, fumed silica and Fe2O3. The obtained composites processed as crosslinked thick (0.60-0.72 mm) films were tested as sensing elements in a nanoactuation device. An interferometric method was used for measurement of the linear displacement of polymeric films by applying a continuum electric field (dc). Displacements of 1600 and 3300 nm were registered under a voltage 475 V..
