The method includes dissolving at least one material in a solvent to form a solution, preparing a coating material by diluting the solution, and spraying the coating material on a subject for spray coating. The spray coating does not need a vacuum chuck, and thus can be applied to a large-sized substrate, and a roll-to-roll method.
