NOVELTY - Method for coating a substrate, involves depositing a conductive layer comprising an electrically conductive material over the substrate, where the conductive layer comprises a resistivity of 10-1000 Ω /hour, and depositing an anti-icing layer comprising nanomaterials over the conductive layer to form a coating system. USE - The method is used for coating a substrate. ADVANTAGE - The method has high conductivity and anti-icing properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) (1) a coating system comprises a conductive layer comprising an electrically conductive material, where the conductive layer comprises a resistivity of 100-1000 Ω /hour and an anti-icing layer comprising a nanomaterial, where the anti-icing layer arranged over the conductive layer; and (2) (2) a composite airfoil comprising a root section comprising a first surface, an intermediate section comprising a first surface and coupled with the root section at a first end, a tip section comprising a first surface and coupled at a first end with a second end of the intermediate section, a coating system arranged over the first surface of the root section, the first surface of the intermediate section, and/or the first surface of the tip section, where the coating system comprises a conductive layer comprising an electrically conductive material, and an anti-icing layer arranged over the conductive layer.
