METHOD FOR APPLYING ZINC OXIDE TO A SUBSTRATE

摘要

A method for applying a zinc oxide coating to a substrate, comprising the steps of: (i) applying a nitrogen-containing aromatic heterocycle functionalised coating to the substrate; (ii) contacting the nitrogen-containing aromatic heterocycle functionalised coating with an agent comprising palladium(II) and/or platinum(II), resulting in a coating comprising complexed palladium(II) and/or platinum(II); (iii) reducing the complexed palladium(II) and/or platinum(II) in the coating to palladium(0) and/or platinum(0); and (iv) contacting the coating comprising complexed palladium(0) and/or platinum(0) with a zinc salt in the presence of a reducing agent under aqueous conditions to form a zinc oxide coating on the substrate.
