Hydrophobic coating including DLC and/or FAS on substrate

Abstract

A substrate is coated with a hydrophobic coating system including diamond-like carbon (DLC) and at least one fluoro-alkyl silane (FAS) compound. In certain embodiments, the coating system includes an FAS inclusive layer provided over at least one DLC inclusive layer in order to increase the initial contact angle of the coated article. At least the FAS inclusive layer may be heated (i.e., thermally cured) to an extent sufficient to at least one of: (a) improve the initial contact angle θ of the resulting coated article, (b) render the hydrophobic nature of the resulting coated article more stable when exposed to solution(s)/material(s) such as hexane and/or isopropyl alcohol, and/or (c) improve bonding characteristics of the FAS inclusive layer within itself and/or between the FAS inclusive layer and a layer immediately beneath it.
