Abstract

Heat waves, increasing in frequency, pose significant risks to human health and economic stability. Traditional personal cooling technologies, such as Heating Ventilation and Air Conditioning (HVAC) systems, are energy-intensive and contribute to greenhouse gas emissions, necessitating the development of energy-efficient alternatives. Radiative cooling fabrics (RCFs) could be an ideal method for personal thermal management, while conventional petroleum-based fabrics exhibit low reflectivity and emissivity, limiting their cooling performance. This research introduces hybrid cooling films by incorporating phase change capsules (PCCs) into polypropylene (PP) films treated with a lysozyme-phytic acid coating to enhance hydrophilicity. The resulting RCFs demonstrated significantly improved reflectivity, emissivity and a high latent heat of 108.63 J/g, achieving a cooling performance of 4.62 °C. These findings highlight a scalable approach for manufacturing advanced textiles, contributing to more efficient thermal management strategies in response to rising global temperatures.
