Title (EN) ELECTROMECHANICAL MATERIALS AND DEVICES INCLUDING THE SAME
(FR) MATÉRIAUX ÉLECTROMÉCANIQUES ET DISPOSITIFS LES COMPORTANT
Abstract:
(EN) An electromechanical article that includes a composite material (110) including a polymer and at least one expanded microsphere having an outer shell of a shell material and a gas contained within the outer shell, wherein the polymer at least partially encapsulates the microsphere and wherein the polymer, shell material and gas all have different dielectric constants. Devices including such articles and methods of making the articles are also disclosed.
(FR) La présente invention concerne un article électromécanique qui comprend un matériau composite (110) comportant un polymère et au moins une microsphère expansée dotée d'une coque extérieure en matériau de coque et un gaz contenu dans la coque extérieure. Le polymère encapsule au moins partiellement la microsphère. Le polymère, le matériau de coque et le gaz possèdent tous des constantes diélectriques différentes. L'invention concerne également des dispositifs qui comprennent lesdits articles et des procédés de fabrication des articles.
