Photocatalytic Inks

Titanium dioxide is an extremely inexpensive material that is produced in very large quantities with numerous industrial applications including paints, sunscreens, catalysis and optical coatings. In most cases the titanium dioxide is embedded within an organic structure; however, these are rarely used in applications requiring durable films. In order to achieve a robust film for extreme operating environments, it is advantageous to have a fully inorganic film. We have developed a unique formulation composed of an industrial source of titanium dioxide powder and an inorganic-organic binder dispersed into water. This ink can be deposited using a number of traditional printing techniques and the organics can be removed in downstream processes such as ultraviolet radiation, intense pulsed light, atmospheric plasma and thermal processes. The viscosity of the inks and the overall porosity of the thin films can be engineered to specific specifications.
