Electrospinning Machine | Multimodal Super-Cooling Textiles for All-Scenario Passive Hygrothermal Comfort

Challenge: Under the circumstance of continuously rising global temperatures, radiative cooling textiles are promising for achieving personal thermal comfort, improving productivity, and saving energy. However, despite extensive research, most advanced radiative cooling textiles only possess radiative functions and cannot achieve efficient cooling in all situations, especially when high temperature and high humidity reduce non-radiative cooling capacity. 

Method: Professor Ding Bin and Professor Wang Xianfeng from Donghua University proposed a multimodal super-cooling textile that integrates radiative, conductive, and evaporative mechanisms through a 3D cladding strategy to enhance cooling effects in various scenarios without compromising radiative performance. 

Innovation 1: This method, through high backscattering efficiency, a three-dimensional thermal conduction network structure, and a Janus wetting structure, enables all one-dimensional single fiber surfaces to be tightly 3D-clad with two-dimensional boron nitride nanosheets, thereby achieving ultra-high solar reflectance (97.30%), omnidirectional heat dissipation (in-plane and out-of-plane thermal conductivity of 2.40 and 0.33 W m−1 K−1, respectively), and unidirectional moisture transport performance (transport index of 1547%). 

Innovation 2: Through multiple cooling mechanisms, the MST reduces temperature by 20°C compared to cotton under outdoor sunlight. Even in hot and humid environments, it still provides a 2°C cooling advantage over cotton.
