Starting from three-dimensional structure design, the Nanjing University team proposed a phase inversion method combined with self-deposition preparation technology, and successfully obtained a new material built of microporous polymer single-sided directionally enriched SiO2 microspheres. Its unique new structure gives the material excellent Radiation cooling performance; In particular, the material can be deposited and formed on the surfaces of different substrates such as metals, wood, plastics, and fiber fabrics to achieve efficient cooling and energy conservation, providing new ideas for the development of high-performance radiation-cooled passive cooling materials; this material can not only form a self-supporting film, but also is similar to painting paint on the surface of the substrate, which has good industrial application prospects. At the same time, this preparation technology has the advantages of low cost, simple process, and suitable for large-scale production. The prepared material can not only be self-supporting, but also can deposit and form films on the surfaces of various base materials like coatings, thereby achieving high efficiency. The purpose of cooling and energy saving.
Radiant cooling technology refers to the ability to cool objects by radiating heat into outer space without using energy. Currently, the technology is being tested on a small-scale at Dagu Glacier in Sichuan to try to slow down the melting rate of the glacier
