First Claim
1. A method of making a coated article comprising a graphene-inclusive film on a substrate, the method comprising:
- disposing a metal-inclusive catalyst layer on the substrate;
heating the substrate with the metal-inclusive catalyst layer thereon;
exposing the substrate with the catalyst layer thereon to a carbon-inclusive precursor gas;
annealing the substrate with the catalyst layer thereon at a temperature of 350-600 degrees C. for a time period of 10 minutes to 3 hours; and
forming graphene over and contacting the metal-inclusive catalyst layer, and between the substrate and the metal-inclusive catalyst layer, in making the coated article.

Abstract
Certain example embodiments relate to methods for large area graphene precipitation onto glass, and associated articles/devices. For example, coated articles including graphene-inclusive films on substrates, and/or methods of making the same, are provided. A metal-inclusive catalyst layer (e.g., of or including Ni and/or the like) is disposed on the substrate. The substrate with the catalyst layer thereon is exposed to a precursor gas and a strain-inducing gas at a temperature of no more than 350-600 degrees C. for 10s or 100s of minutes. Graphene is formed and/or allowed to form both over and contacting the catalyst layer, and between the substrate and the catalyst layer, in making the coated article. The catalyst layer, together with graphene formed thereon, is removed, e.g., through excessive strain introduced into the catalyst layer as associated with the graphene formation. Products including such articles, and/or methods of making the same, also are contemplated.
