Latest Patents

Kimijima holds a patent for a "Method for forming titanium oxide film on surface of molded product composed of cyclic olefin resin." This method allows for the formation of a titanium oxide film on a base material without the need for a heating step. The process involves irradiating the surface of a molded product made from cyclic olefin-based resin with ultraviolet light in an air atmosphere. Following this, the base material is immersed in a mixed liquid of an aqueous solution of titanium chloride and a nitrite ion-containing aqueous solution. The titanium oxide film grows through the oxidation of titanium ions, and the film thickness can be controlled by adjusting the immersion time. After washing, the base material is dried at room temperature.
