Özet

Recently, passive heating textiles that manage sunlight and radiation energy without consuming energy have attracted attention as a potential solution for personal thermal management in cold environments. However, static solar energy and/or radiation heating performance may negatively affect comfort and human health. Therefore, there is a need for adaptive textiles that can provide comfort and safety in relation to temperature increase and sweating in cold environments. Herein, passive radiative-solar heating textiles with adaptive permeability were developed by coating viscose nonwoven fabrics (CV-NFs) through composite including fibroin (SF) obtained from upcycled waste silkworm cocoons and rose-water reduced graphene oxide (rGO) particles. Notably, fabrics coated with SF-rGO4 composite containing 4 wt.% particle, exhibited passive radiative heating performance with temperature increase of 2.01°C due to lower mid-infrared emissivity. Also, these samples demonstrated temperature increase of 5.79°C under 0.6 sun irradiation and 10.83°C under real outdoor conditions, respectively thanks to higher solar absorptivity. Besides radiative-solar heating capability and mechanical strength, adaptive comfort feature was been achieved via humidity hence sweat-sensitive permeability by virtue of SF-rGO composite coating. Based on these results, this study offers a sustainable strategy for developing heating textiles with adaptive permeability performance through upcycling of waste silkworm cocoons and eco-friendly reduction method.
