Tsinghua University’s Prof. Zhang Rufan ACS Nano (IF 15.8): Radiative Cooling Super-Fabric Integrating Knit-Wicking and Coating Thermal Conduction

Challenge: Radiative cooling is an emerging zero-energy technology for body cooling in hot outdoor environments. However, existing radiative cooling textiles suffer from low intrinsic cooling power, high hydrophobicity, and thermal insulation, severely impairing cooling efficiency, sweat expulsion, and heat dissipation, thus limiting human thermal comfort in practical use.
Approach: Prof. Zhang Rufan from Tsinghua University integrated carbon nanotubes with an electrospun PVDF-HFP membrane to design a super-fabric material with selective thermal radiation, sweat-wicking, and heat conduction.
Innovation 1: This super-fabric rapidly absorbs sweat from the skin and transports it outward, while its high thermal conductivity (1.5 W/(m·K)) prevents overheating in high-temperature environments, achieving superior cooling (10.9 °C lower than non-sweating conditions).
Innovation 2: Even without sweat, the super-fabric cools 9.6 °C more than commercial cotton, offering a novel approach to practical personal thermal management textiles.
