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.
