GRAPHENE NANORIBBON LAYERS FOR DE-ICING AND ANTI-ICING APPLICATIONS

摘要

The present disclosure pertains to methods of preventing or reducing ice formation on a surface by applying a graphene nanoribbon-containing composition to the surface to form a layer associated with the surface. The formed layer can have water contact angles of 150 degrees, electrical conductivities of 100 S/m, and resistances of 500 Ω/sq. The graphene nanoribbons associated with the layer can include a network of graphene nanoribbons that define an electrical pathway. The graphene nanoribbons may constitute 5 wt% of the layer. The layer can prevent ice formation by repulsion of water from the layer. The layer can reduce ice formation by melting ice from the surface through application of a voltage to the layer (either from an external voltage source or a magnetic field from an electrically conductive structure). The present disclosure also pertains to surfaces that include the aforementioned layers.
