In industrial applications, functional pigments are used for their unique properties such as color, opacity, and UV blocking capabilities. They are commonly used in the production of paints, coatings, plastics, ceramics, and other materials. Our laboratory focuses on designing and applying compositions of inorganic pigments with the optical properties required for various applications. NIR (Near Infrared) reflective pigments are a type of functional pigment that reflects light in the near-infrared region of the electromagnetic spectrum (wavelengths of 700-2500 nm). These pigments are used in a variety of applications, particularly in coatings, plastics, and printing inks, where they provide unique functional properties such as heat management, camouflage, and security. We are conducting research on designing black pigments with excellent LiDAR response performance for autonomous driving cars, by controlling the nanostructure to manipulate the LiDAR reflectance. In addition, we are designing highly near-infrared reflective pigments with excellent heat shielding properties through spray pyrolysis.
