Wearable Tailored Passive Radiative Cooling Textile for Flexible Electronic Integration

Area of Science:

• Materials Science
• Textile Engineering
• Wearable Technology

Background:

• Conventional textiles lack thermal management for wearable electronics.
• Existing materials compromise comfort, breathability, or safety when integrating electronics.

Purpose of the Study:

• To develop a wearable textile for seamless electronic integration.
• To address the thermal-optical demands of embedded electronics.
• To enhance wearer safety and device performance.

Main Methods:

• Fabrication of a wearable tailored passive radiative cooling textile (WRCT) using a scalable, one-step wet-spinning technique.
• Utilizing hierarchical phase inversion kinetics to create microfibers with multiscale porosity and surface nodules.
• Characterization of solar reflectance and mid-infrared emissivity.

Main Results:

• Achieved high solar reflectance (>95%) and mid-infrared emissivity (0.96) with the WRCT.
• Demonstrated breathability, flexibility, and passive daytime thermal management.
• Maintained skin temperature below 41°C under intense sunlight and high localized heat flux, preventing burns.

Conclusions:

• The WRCT platform integrates flexible electronics, offering comfort and safety.
• This textile provides a practical, scalable foundation for reliable wearable electronic systems.
• The material acts as an advanced thermal-optical regulator for electronic textiles.
