A substrate is coated with a hydrophobic layer(s) that includes, for example, highly tetrahedral amorphous carbon that is a form of diamond-like carbon (DLC), or any other suitable material. In certain embodiments, the exterior surface of the resulting coated article exhibits a surface roughness sufficient so that the article has an initial contact angle .theta. of at least about 100 degrees. In certain embodiments, the layer has a surface energy of no more than about 20.2 mN/m and/or an average hardness of at least about 10 GPa.

[ I claim:] [1.]1. A coated glass article comprising:a glass substrate;a hydrophobic coating including diamond-like carbon (DLC) and sp.sup.3 carbon--carbon bonds provided on said glass substrate; andwherein an exterior surface of said hydrophobic coating includes peaks and valleys defined therein wherein peaks at the exterior surface of the coating have an average height "d" of from about 5-60 nm, said peaks and valleys being of sufficient size so that the hydrophobic coating has an initial contact angle .theta. with a sessile drop of water thereon of at least about 100 degrees.
