The Saharan silver ant has developed a unique method for maintaining a cool body temperature. This is achieved through a combination of enhanced optical reflection and radiative heat dissipation. The surface hairs of the ant have a distinctive structure that permits sunlight to penetrate the top layer, internally reflect, and emit heat energy into space as infrared radiation. This process enables the ant to regulate its body temperature and survive in the scorching heat of the desert.
Inspired by the skin structure with the self-cooling function of the Saharan silver ant, i2Cool invented passive radiative cooling technology that can reflect most of the solar heat while effectively emitting thermal energy as mid-infrared to the cold universe.
After seven years of continuous experimentation and scientific research by the i2Cool team, we have finally solved the difficulties of high costs for developing and applying passive radiation cooling technology, difficulties in mass production and technical barriers to the construction process. The research results have been successfully transformed into a commercially available product for large-scale application - Radiative Cooling Film (iFilm)
