Latest Patents

Arifuku's latest patents include an infrared shielding sheet and a method for manufacturing the same. This infrared shielding sheet features a laminated film formed by alternately layering a high refractive index resin containing fine particles and a low refractive index resin also containing fine particles. Notably, at least one of the low refractive index resin layers has a specific refractive index value that is derived from subtracting a refractive index at an arbitrary wavelength from 780 to 2500 nm from a refractive index at a wavelength of 550 nm. This design ensures that the low refractive index resin layer maintains a refractive index lower than that of the high refractive index resin layer across a specified wavelength range.

Another significant patent involves a process for producing high-purity single-walled carbon nanotubes. This innovative method utilizes chemical vapor deposition (CVD) and employs nonmetallic materials with minimal metallic impurities as growth nuclei. The process is designed to yield highly pure, high-quality single-walled carbon nanotubes efficiently. Additionally, a transparent conductive film utilizing these carbon nanotubes has been developed, showcasing the practical applications of Arifuku's research.
