Radiation refrigeration film and preparation method thereof
The invention discloses a radiation refrigeration film and a preparation method thereof, the radiation refrigeration film comprises a first polymer layer, nanoparticles are dispersed in the first polymer layer, and the first polymer layer comprises a substrate layer and a micron pyramid array located on the substrate layer; the second polymer layer is at least arranged on the surface of the micron pyramid in the micron pyramid array; the first polymer in the first polymer layer comprises at least one of polydimethylsiloxane, polyurethane, polyethylene and polyethylene terephthalate, and the nano-particles comprise at least one of titanium dioxide nano-particles, aluminum oxide nano-particles, silicon dioxide nano-particles and polyvinylidene fluoride nano-particles; and the second polymer layer is a polyvinylidene fluoride layer. The radiation refrigeration film has strong reflection in a solar wave band and strong emission in an atmospheric window, so that daytime radiation refrigeration is realized, and the radiation refrigeration film can be attached to a building to endow the building with good radiation refrigeration performance.
本发明公开一种辐射制冷薄膜及其制备方法，所述辐射制冷薄膜包括：第一聚合物层，第一聚合物层中分散有纳米颗粒，第一聚合物层包括基底层以及位于基底层上的微米金字塔阵列；第二聚合物层，至少设置在微米金字塔阵列中的微米金字塔表面上；第一聚合物层中的第一聚合物包括聚二甲基硅氧烷、聚氨酯、聚乙烯、聚对苯二甲酸乙二酯中的至少一种，纳米颗粒包括二氧化钛纳米颗粒、氧化铝纳米颗粒、二氧化硅纳米颗粒、聚偏氟乙烯纳米颗粒中的至少一种；第二聚合物层为聚偏氟乙烯层。该辐射制冷薄膜在太阳波段具有较强的反射，在大气窗口内具有较强的发射，从而实现日间辐射制冷，该辐射制冷薄膜可以附着在建筑物上，赋予建筑物良好的辐射制冷性能。
