Abstract:
1. A chemical vapor deposition method of forming a layer upon a surface of a substrate, which layer provides a topography over said substrate surface which can be tailored to provide a super-hydrophobic property or a super-hydrophilic property, wherein the topography which enables the super-hydrophobic or super-hydrophilic property is created by controlling chemical vapor deposition process parameters, including the chemical composition of the reactants, the relative amounts of the reactants, the process pressure, the process temperature, and the reaction time, such that nano-particles are produced in a vapor phase over the substrate surface and are deposited on said substrate surface in a controlled manner, to produce a surface topography which exhibits said super-hydrophobic or said super-hydrophilic property.
