Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed and results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

Abstract: Glass surfaces, for example, windshield surfaces, have a durable hydrophobic coating applied thereto. The glass surface is first treated by any suitable method to enhance the ability of a chitosan polymer coating to durably or substantially permanently adhere thereto. Once the chitosan coating has been applied to the glass surface, the normally hydrophilic chitosan coating is rendered hydrophobic by suitable treatment, for example, by a combination of enzymatic and chemical treatments. Alternatively, the chitosan may be rendered hydrophobic prior to coating it on the glass surface, but that is a less preferred technique. The method of the invention provides a glass article having a hydrophobic surface.
