ABSTRACT:
The invention provides a method for synthesizing a titanium oxide-containing film comprising the following steps:
(a) preparing an aqueous solution of a titanium chelate with a titanium molarity in the range of 0.01M to 0.6M.
(b) immersing a substrate in the prepared solution,
(c) decomposing the titanium chelate to deposit a film on the substrate.
The titanium chelate maybe decomposed acid, base, temperature or other means. A preferred method provides for the deposit of adherent titanium oxide films from C2 to C5 hydroxy carboxylic acids. In another aspect the invention is a novel article of manufacture having a titanium coating which protects the substrate against ultraviolet damage. In another aspect the invention provides novel semipermeable gas separation membranes, and a method for producing them.
