The development of scalable high-quality radiative cooling materials can

effectively address overheating issues without energy consumption. While

some progress has been made, significant challenges remain in a narrow

application range, low cooling power, and poor mechanical properties, which

fail to meet requirements for sustainable use. Here, inspired by the special

structure of white moth wings and spider silk, a flexible, strong, and tough

high-efficiency radiation cooling metafabric (STRCM) is demonstrated with a

unique fiber microstructure (including anisotropy and core–shell structure).

The metafabric exhibits remarkable mechanical characteristics, boasting an

effective tensile strength of 2.55 MPa, and exceptional toughness with an

elongation at break of 726.94% and an impact energy absorption of 31

MJ m?3. More importantly, the metafabric demonstrates excellent radiative

cooling with a temperature drop of ≈6.7 °C and an average cooling power of

79.0 W m?2 under a peak solar intensity of ≈978 W m?2 (tested in Beijing,

China). During a long-term intermittent testing period, the cooling effect of

the material shows no noticeable decline. The multi-level structural design of

this work provides an unprecedented strategy for simultaneously enhancing

mechanical properties and radiative cooling for long-term applications.
