Infrared radiation primarily contributes to the rise in car temperature, prompting excessive reliance on air conditioning, which in turn increases fuel consumption and emissions of harmful gases. Various methods exist to mitigate this, including the application of inorganic pigments designed to reflect infrared radiation. Proposed solution: silica nano and microparticlesThe proposed solution involves utilising silica nano/microparticles known for their transparency in the visible spectrum and high reflectivity to infrared radiation. The most successful material developed showcases an impressive ability to increase the infrared radiation reflection and decrease the temperature by roughly 27 °C. This study demonstrates a promising alternative to minimize the use of air conditioning systems and subsequently reduce the emission of polluting gases.
