超疏水自清洁辐射散热膜的制备
Fabrication of radiative cooling film with superhydrophobic self-cleaning property
中文简介
辐射制冷材料可以在没有任何能量输入的情况下对地面物体进行降温,但容易受到雨水浸湿和灰尘污染,严重影响其制冷特性。在此,这项工作使用聚(偏二氟乙烯)制备了具有超疏水自清洁性能的辐射冷却多孔膜。-六氟丙烯)(PVDF-HFP)和聚(偏二氟乙烯)(PVDF)。PVDF-HFP/PVDF 薄膜由内部和表面均带有纳米粒子的微孔组成。微/纳米结构增强了太阳光的散射,这与 PVDF-HFP 和 PVDF 聚合物的红外发射率相结合,使薄膜显示出出色的辐射冷却能力,温度可下降 16°C。微/纳米结构使薄膜表面粗糙,结合 PVDF-HFP 和 PVDF 聚合物的低表面能特性,赋予薄膜超疏水自清洁性能。自清洁功能可保护薄膜免受污染,并为持久应用保持可持续的辐射冷却。
英文摘要(原文)
Radiative cooling materials can cool terrestrial objects without any energy input but are susceptible to rain wetting and dust contamination, which affects badly their cooling characteristics. Herein, this work fabricated a radiative cooling porous film with superhydrophobic self-cleaning properties using poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinylidene fluoride) (PVDF)
