本刊讯日前,美国科学家研制出一种新的多层涂层,几乎能够反射太阳光带来的全部能量,并能吸收来自建筑物内部的热量,在不使周围空气升温的前提下将其辐射殆尽。据悉,这种新材料能够辐射长波长能量的反射镜镀层,其研究团队制造出一种交替着二氧化硅和二氧化铪的7层薄膜,总厚度不超过2微米。在实验中,研究人员把这种材料置于建筑物屋顶,它能同时把建筑物内部的红外光散射出去,并反射外部太阳光。在多项测试中,即便在全日照的情况下,这
Recently, the United States scientists have developed a new multi-layer coating, almost able to reflect all the energy brought by sunlight, and can absorb heat from the interior of the building, without increasing the ambient air under the premise of its Radiation exhausted. It is reported that this new material can radiate long wavelength energy mirror coating, the research team to create a alternating layers of silicon dioxide and hafnium oxide film, the total thickness of no more than 2 microns. In experiments, researchers put the material on the roof of a building, which simultaneously scatters the infrared light inside the building and reflects the outside sunlight. In many tests, this is true even in full sunlight
