Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="mabi201300457-sec-0001" sec-type="section"> <p>A low‐viscosity, solvent‐free process for the fabrication of thin silicone films for dielectric elastomer actuators is presented. Octamethylcyclotetrasiloxane and specially designed co‐monomers that function as cross‐linkers are pre‐polymerized to a liquid of low viscosity. This liquid is used to prepare thin films, which are then fully polymerized to a highly transparent, cross‐linked elastomer. The mechanical and electromechanical properties of the films are easily tuned by altering the amount of cross‐linker co‐monomer used.<inline-graphic xlink:href="ark:/27927/pgh177nfn9s" content-type="mame201300457-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
