FTAs:
Now materials scientists have developed a color-changing film that can switch between heating and cooling modes. The film, which is thinner than a credit card, operates on very little energy and could one day envelop even the most wasteful of buildings to help radiate unwanted heat in the summer and trap it in during the winter.
researcher Debashis Chanda, a professor in UCF’s NanoScience Technology Center, has drawn inspiration from butterflies to create the first environmentally friendly, large-scale and multicolor alternative to pigment-based colorants, which can contribute to energy-saving efforts and help reduce global warming.
