An electrically conductive coating composition is provided for use on aircraft and other substrate surfaces to prevent the formation of ice or to melt ice. The conductive coating composition may include a nanomaterial such as carbon nanotubes dispersed in a solvent which may be applied to a substrate surface to form a thin film which is resistively heatable. The conductive coating may also comprise a nanomaterial formed from carbon nanotubes or fullerenes grafted to a polymer containing an active functional group which renders a substrate surface icephobic and is also resistively heatable. L'invention concerne une composition de revêtement électriquement conductrice à utiliser sur un avion et sur d'autres surfaces de substrat en vue d'éviter la formation de glace ou de faire fondre de la glace. La composition de revêtement conductrice peut inclure un nanomatériau tel que des nanotubes de carbone dispersés dans un solvant appliqué sur une surface de substrat pour former un mince film qui peut être chauffé de manière résistive. Le revêtement conducteur peut également inclure un nanomatériau formé de nanotubes de carbone ou de fullerènes greffés sur un polymère contenant un groupe fonctionnel actif qui prévient la formation de glace sur une surface de substrat et peut également être chauffée de manière résistive.
