Abstract
A hydrophobic surface comprises a surface texture and a coating disposed on the surface texture, wherein the coating comprises an amorphous diamond like carbon material doped with 10 to 35 atomic percent of Si, O, F, or a combination comprising at least one of the foregoing, or a low surface energy material selected from fluoropolymer, silicone, ceramic, fluoropolymer composite, or a combination comprising at least one of the foregoing; and wherein the surface texture comprises a micro texture, a micro-nano texture, or a combination of a micro texture and a micro-nano texture.
Claims23
A hydrophobic surface comprising a surface texture and a coating disposed on the surface texture, wherein the coating comprises an amorphous diamond like carbon material doped with 10 to 35 atomic percent of Si, O, F, or a combination comprising at least one of the foregoing, or a low surface energy material selected from fluoropolymer, silicone, ceramic, fluoropolymer composite, or a combination comprising at least one of the foregoing;
- and wherein the surface texture comprises a micro texture, a micro-nano texture, or a combination of a micro texture and a micro-nano texture.
A hydrophobic surface comprising a coating disposed on an un-textured surface, wherein the coating comprises an amorphous diamond like carbon material doped with 10 to 35 atomic percent of Si, O, F, or combination thereof, and wherein the un-textured surface comprises a metal.
A method of producing a hydrophobic surface, the method comprising forming a texture on a surface of a substrate to provide a textured surface, disposing a coating on the textured surface, wherein the coating comprises an amorphous diamond like carbon material doped with 10 to 35 atomic percent of Si, O, F, or a combination comprising at least one of the foregoing, or a low surface energy material selected from fluoropolymer, silicone, ceramic, fluoropolymer composite, or a combination comprising at least one of the foregoing.
