Abstract:
Conventional radiative cooling materials often suffer from limited functionality, poor environmental adaptability, and insufficient integration of thermal regulation with moisture management. Inspired by the layered and hierarchical organization of human skin, we designed a hierarchically structured composite material via electrospinning and electrospraying to achieve multifunctional personal thermal-moisture management. Polyamide nanofibers with controllable hydrophobic porous structures were first fabricated through a one-step electrospinning process using ethanol as a green solvent. Subsequently, precise control of charged droplet ejection enabled the uniform deposition of functional nanospheres onto the fiber surfaces, synergistically enhancing broadband solar reflectance and infrared thermal emission. The resulting composite exhibited excellent radiative cooling performance, achieving a solar reflectance of 97.3%, an infrared emissivity of 91.3%, and a temperature reduction of 7.3°C under identical conditions, outperforming conventional cotton fabrics. Meanwhile, high water resistance (67.4 kPa) and a moisture vapor transmission rate of 7.8 kg·m-2·d-1 were simultaneously realized, enabling an effective balance between wearing comfort and environmental protection. Notably, the entirely green-solvent-based fabrication process provides a scalable and sustainable pathway for advanced thermal management textiles.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...
