Abstract
A method of forming a hydrophobic surface is disclosed. The method comprises coating a substrate surface with a stable aqueous colloidal solution, formed by a controlled hydrolysis and nucleation reaction, comprising insoluble hydrous oxide particles of an element selected from Be, In, Cr, Fe, Co, Ni, Tl, Cu, Zn, Sn and mixtures thereof. The coated surface is then exposed to a source of ultraviolet radiation having a wavelength ranging from 1800A to 3300A to render exposed surface regions hydrophobic.
