Method of making coated article including diamond-like carbon (DLC) and FAS
First Claim
1. A method of making a coated article comprising:
- providing a substrate;
forming a coating system on the substrate so that the coating system includes each of diamond-like carbon (DLC) and at least one fluoro-alkyl silane (FAS) compound; and
heating at least an FAS compound portion on the coating system to a temperature and for a period of time sufficient to increase an initial contact angle θ
of the resulting coated article.

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.
