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.
An electrically conductive coating composition dispersed in a liquid carrier for use on substrates comprising a nanomaterial selected from carbon nanotubes, metal nanorods, functionalized metal nanoparticles, and a nanostructure comprising carbon nanotubes or fullerenes grafted to a polymer containing an active functional group;
A substrate having a resistively heatable film thereon, said film comprising an electrically conductive coating composition comprising a nanomaterial selected from carbon nanotubes, metal nanorods, and functionalized metal nanoparticles, and a nanostructure comprising carbon nanotubes or fullerenes grafted to a polymer containing an active functional group, said film having a sheet resistance of from about 0.01 to about 1000 ohm/sq.
A substrate having a multilayer coating thereon which is resistively heatable to prevent the formation of ice or to melt ice on the surface of said substrate comprising:
A method of preventing the formation of ice on, or melting ice from, the surface of a substrate comprising:
