▎ 摘　　要

NOVELTY - Airfoil comprises a root section (102), an intermediate section (104) coupled with the root section, a tip section coupled with the intermediate section, and a layer arranged on the root section, the intermediate section, and/or the tip section, and comprising a carbon allotrope material, an electrically conductive material arranged on the carbon allotrope material, and comprising a polymer and a sulfonic acid, and a wear-resistant material layer adjacent the layer comprising the carbon allotrope material and the electrically conductive material. The carbon allotrope material is a carbon allotrope material sheet. USE - Airfoil. ADVANTAGE - The airfoil reduces overall energy demand of heaters of rotor blade, reduceS energy consumption, reduces amount of solvent for deposition provides faster curing times, and reduces costs of production. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view of an airfoil. Root section (102) Intermediate section (104)
