Nagoya University Develops Highest Performance Solar Shielding Film Using Tungsten Trioxide 166

Professor Minoru Nagata of Nagoya University and others have developed a thin film plate that can reflect about 50% of near-infrared light. This film board can transmit visible light, but its blocking ability for near-infrared light from solar heat sources is more than twice that of traditional products. If used in construction and automobile window materials, it can effectively regulate the temperature indoors or in the car. Currently, we are cooperating with material manufacturers to develop the sun visor to…
