By Shaoning Zeng et al they choose a material chosen, a composite of titanium oxide and polylactic acid (TiO2-PLA) with a polytetrafluoroethylene (PTFE) lamination, was pivotal in achieving the desired optical characteristics. The fabric underwent thorough optical and thermal characterization, measuring essential properties like reflectivity and emissivity. Numerical simulations, including Lorenz-Mie theory and Monte Carlo simulations, were crucial in predicting the fabric's performance and guiding its optimization. Additionally, mechanical testing was conducted to ensure the fabric's durability, strength, and practicality for everyday use.
