Abstract

Abstract

Flexible electrode of dielectric elastomer actuator (DEA) plays important roles in generating electric fields and constraining dielectric matrix deformation. By using one-dimensional multi-wall carbon nanotubes (MWCNT) and zero-dimensional conductive carbon black (CB) as co-conductive fillers, a series of polydimethyl siloxane (PDMS) composite electrode films (MWCNT-CB/PDMS) were designed with varying size, mechanical and electrical properties. The electrode films were adhered to the lateral surfaces of a polyvinyl chloride gel matrix film and imported into a pulsed high-voltage signal to obtain novel dielectric polymer actuators with various electromechanical behaviors. Tests of electromechanical properties reveal that, the increase of electrode coverage is beneficial to DEA’s strain, the increase of electrode thickness hampers its strain, while the strain exhibits an initial increase following decrease trend with increasing MWCNT loading. Orthogonal experiments show that, the MWCNT loading has a significant effect on the displacement output, while the electrode coverage and thickness present high-level significances to the displacement output. Under the optimal condition, the displacement output of DEA is 1.71 mm at maximum.
