Abstract
Disclosed herein are embodiments of a coating composition and a method of using the same for forming metal coatings on substrates. In particular embodiments, the coating composition comprises a deep eutectic solvent and/or an ionic liquid; a metal precursor; an alkali metal salt; and an optional additive component. The coating composition and method embodiments disclosed herein provide durable, even, high-surface area coatings on various types of substrates and also can be used at low temperatures.
Claims19
