Spin coating high quality thin films from aqueous precursors is highly dependent on the surface chemistry of the substrate. In this study, the influence of the surface hydrophilicity of indium tin oxide substrates on cobalt phosphate thin films deposited by spin coating aqueous precursor solutions was explored. The hydrophilicity of the substrate surface was controlled by applying varying voltages between the indium tin oxide surface and a stainless steel electrode in a sulfuric acid electrolyte. The hydrophilicity of the surfaces was measured by the contact angle of water drops resting on the substrate surface. Thin films of cobalt phosphate were spin coated onto the substrate surfaces prepared with different hydrophilicities to explore the influence of the surface chemistry on the quality of the films.
