Temperature-adaptive dual-modal photonic textiles for thermal management

Area of Science:

• Materials Science
• Textile Engineering
• Renewable Energy

Background:

• Maintaining thermal comfort is vital for human health and productivity.
• Current methods for thermal regulation in textiles often require external energy sources or active interventions.
• Developing self-regulating textiles is a key challenge for sustainable living environments.

Purpose of the Study:

• To create a dual-modal photonic textile for autonomous thermal management.
• To investigate the textile's capability for both solar heating and radiative cooling.
• To assess the textile's performance in real-world applications for enhanced thermal comfort.

Main Methods:

• Functionalizing textile fibers with thermochromic microcapsules coated in graphene and barium sulfate.
• Integrating these functionalized fibers into a fabric structure.
• Fabricating garments and a tent from the developed textile for performance testing.

Main Results:

• The photonic textile demonstrated significant visible light optical modulation (approx. 80%).
• Garments and tents made from the textile achieved temperature-adaptive, all-weather thermal management.
• The textile expanded the thermal comfort range by 8.5°C.

Conclusions:

• The developed dual-modal photonic textile offers autonomous, passive thermal regulation.
• This innovation has significant potential for fabric-based heat management solutions.
• The research supports the development of sustainable and healthy lifestyles through advanced textiles.
