Additionally, the material can be processed into various shapes of titanium metal, including sheets, meshes, and beads, and can also be regenerated, making it suitable for a wide range of applications. 【Features】 ■ Excellent deodorizing, antibacterial, and anti-soiling effects ■ High hydrophilicity of the surface makes it suitable for long-term outdoor use ■ Lightweight, strong, highly corrosion-resistant, and non-magnetic ■ Excellent design properties, allowing for wide application in various locations ■ Can be processed into various shapes of titanium metal *For more details, please download the PDF or feel free to contact us.

Titanistar undergoes surface oxidation treatment on pure titanium, which is the metal titanium. A photocatalytic film free of impurities grows from the surface of pure titanium without any interface. In other words, the pure titanium substrate becomes TiO2 through surface oxidation treatment. Observations were conducted using optical instruments on the Titanistar photocatalytic film. - Surface observation using an electron microscope: The surface of Titanistar is porous and cluster-like, and it was found that the film grows from pure titanium without any interface. - Control of crystal structure: Titanistar can control its crystal structure. It can be adjusted to exhibit higher photocatalytic performance with structures such as anatase, rutile, or mixed types. - Observation of surface composition: The surface composition of Titanistar was observed, revealing that it is primarily composed of titanium and oxygen. From the above, it can be concluded that the photocatalyst Titanistar is free of impurities and that the photocatalytic film grows from the surface of the pure titanium substrate without any interface. *For more details, please refer to the PDF document or feel free to contact us.

In general, photocatalysts have the ability to oxidatively decompose organic substances and harmful materials, rendering them harmless. It is said that hydrophilicity occurs on the surface of the photocatalyst in an excited state. We conducted verification tests on these photocatalytic capabilities. - Oxidative Decomposition Ability We treated a non-woven fabric made of pure titanium, cut into 100mm squares, with gas-type Titanister. After sealing it in a Tedlar bag with approximately 250ppm of acetaldehyde gas and reaching adsorption equilibrium, we irradiated it with a 1mW/cm² BLB lamp from above, measuring the concentration of acetaldehyde gas and the concentration of the reaction product, carbon dioxide, at regular intervals. As the concentration of acetaldehyde gas decreased due to Titanister, the concentration of the reaction product, carbon dioxide, increased. Ultimately, it was found that approximately 230ppm of acetaldehyde gas was almost completely decomposed, and a reaction product amounting to twice the concentration of acetaldehyde gas was generated. *For more details, please refer to the PDF document or feel free to contact us.

We report the antibacterial test results against Escherichia coli (E. coli) using the photocatalytic material "Titanistar®." In the photocatalyst industry, tests often last around 3 to 5 hours, so we confirmed the superiority of the antibacterial response through a test set with a short ultraviolet lamp irradiation time of 1 hour. 【Results of the antibacterial test with 1 hour of ultraviolet irradiation】 This time, we conducted an antibacterial test with an irradiation time of 1 hour. Using a strain of E. coli and a film adhesion method with a concentration of 2.5×10^S, we irradiated with 1 mW/cm² BLB. The test area consisted of titanium plates treated with Titanistar, while the control area consisted of untreated pure titanium plates. After 1 hour, no bacterial count could be detected on the Titanistar-treated plates. In contrast, the bacterial count on the untreated titanium plates showed almost no change. This indicates that Titanistar has a high photocatalytic ability. *For more details, please refer to the PDF document or feel free to contact us.

The photocatalytic material "Titanistar(R)" is a photocatalyst produced by applying a unique surface oxidation treatment to pure titanium metal, generating titanium components within pure titanium as photocatalytic titanium dioxide. The substrate is pure titanium metal, not a titanium alloy. Therefore, it is not a coating type and does not use any of these raw materials. - Pure titanium substrate types include plates, meshes, lath meshes, and non-woven fabrics. All of these are flat, but three-dimensional molding processing in specified shapes, such as cylindrical forms, is possible. - Selection and shapes of pure titanium types: From performance and cost perspectives, "lath mesh material" treated with Titanistar is widely used, regardless of liquid phase or gas phase systems. - Titanistar series: - Titanistar MI=O: Dedicated for interference color effects. It has lower performance within the series. - Titanistar MI-W: Gas phase reaction type. Focused on performance. - Titanistar MI-C: Liquid phase reaction type. Thickness of the film. Highest performance class in the series. *For more details, please refer to the PDF document or feel free to contact us.
