In order to advance the real-world adaptation of energy-saving and thermoregulating textiles, limitations such as form factors, application methods, and material sustainability must be addressed. Here, fabrication methods for extremely light and thin solar reflective textile are explored from electrospinning to demonstrate the effects of structural modifications on the optical properties of nano/microfibers. UV-protective property was further explored which could provide UV protection preventing skin cancer such as melanoma. Results showed that a 2 g/m2 fiber mat composed of porous fibers (PF), with no additional material, blocked 51.24 % of the total solar irradiance and 73 % of UV radiation. With a 7.5 g/m2 PF mat, UV Protective Factor (UPF) was calculated to be ~11 where UPF of surgical mask (~25 g/m2) was calculated to be between 6.5 and 7.endissertation or thesishttps://doi.org/10.7298/kjv0-pn44
