Coated razor blades comprising graphene
A hard coating for a substrate or portion of a razor blade wherein a main layer of the hard coating includes graphene and/or any combination of derivatives thereof. The graphene may be deposited on the substrate or portion of the razor blade using plasma assisted chemical vapor deposition (PECVD) or similar process.
1. A razor blade, comprising:
a substrate bearing a cutting edge;
a hard coating disposed on the cutting edge, wherein the hard coating includes a main layer having a graphene or a graphene-based material; and
an outer lubricious coating covering the hard coating that facilitates a reduction in friction between the razor blade and a skin surface of a user,
wherein the graphene-based material is selected from the group consisting of graphite, graphite oxides, graphite nanoplatelets, carbon nanotubes (CNTs), graphene oxides, and any combinations thereof.
2. A shaving device, comprising one or more razor blades of claim 1 .
3. The shaving device of claim 2 , wherein the one or more razor blades include at least one or more strips of stainless steel having at least one cutting edge.
4. The razor blade of claim 1 , wherein the razor blade hard coating further comprises an interlayer below the main layer.
5. The razor blade of claim 1 , wherein the razor blade hard coating further comprises an overcoat layer above the main layer and below the outer lubricious coating.
