Abstract:
1. A method of forming a film coated on a substrate including the steps of: producing a precursor solution by dissolving a film precursor compound in an organic solvent, the film precursor compound comprising at least two hydrolysable groups bonded to a metal or metalloid; coating a substrate with the precursor solution, the film precursor compound therein remaining substantially unhydrolysed; and curing the precursor solution onto the substrate in a gaseous non-neutral pH environment comprising vaporous base, water and an organic solvent to thereby initiate hydrolysis and condensation reactions of the film precursor compound and cause adhesion of the forming film to the substrate, wherein at least one of organic solvent content of the precursor solution and the organic solvent content in the gaseous environment are controlled to control characteristics of the film.
