AI Technical Summary

Technical Problem

Existing fabrics cannot simultaneously achieve stable radiative cooling and rapid perspiration wicking functions, and existing processing methods suffer from poor bonding strength, short service life, and high cost.

Method used

By growing SiO2 nanoparticles in situ on the surface of cellulose fabric, and spraying an alkaline solution on one side to construct a hydrophilic surface and cellulose acetate on the other side to construct a hydrophobic surface, a stable hydrophilic-hydrophobic structure is formed. Combined with Mie scattering theory, reflectivity and emissivity are improved.

Benefits of technology

It achieves all-weather, multi-scenario self-cooling function. The cellulose fabric has high reflectivity in the visible-near infrared band and high emissivity in the mid-infrared band, and has long-term stability and durability, and can effectively cool down in different environments.
