中文简介

辐射冷却纺织品被越来越广泛地认为是一种有效的节能热调节策略。在本研究中,我们介绍了一种新型的辐射冷却纺织品,PTFE/SiO2@Cotton,通过在棉织物上原位合成二氧化硅颗粒,然后涂覆聚四氟乙烯(PTFE)而制成。SiO2 纳米粒子的原位生长显著提高了织物的耐用性,确保在各种环境条件下长期稳定。设计的双层结构,利用了 PTFE(n=1.29)和 SiO2(n=1.47)之间的折射率差异,增强了阳光的背散射,在可见光范围内(0.2-2.5 微米)实现了显著的太阳能反射率 80.2%。PTFE/SiO2@Cotton 织物在第一(8∼13 微米)和第二(16∼25 微米)大气窗口中表现出高发射率,4∼25 微米范围内的平均发射率为 97.8%。这种双窗口发射在干燥和潮湿气候下都提供了有效的辐射冷却,使其适应各种环境条件。 在模拟阳光下,PTFE/ SiO2@棉织物与未改性的棉织物相比,温度降低了高达

英文摘要(原文)

Radiative cooling textiles are increasingly recognized as an effective strategy for energy-efficient thermal regulation. In this study, we present a novel radiative cooling textile, PTFE/SiO2@Cotton, fabricated through in-situ synthesis of silica particles on cotton fabric followed by a polytetrafluoroethylene (PTFE) coating. The in-situ growth of SiO2 nanoparticles significantly improved the durability
