Adaptive IR- and Water-Gating Textiles Based on Shape Memory Fibers

Area of Science:

• Materials Science
• Textile Engineering
• Biomedical Engineering

Background:

• Thermoregulation is vital for human health, requiring adaptation to environmental temperature shifts.
• Smart textiles offer potential for dynamic protection against fluctuating temperatures.
• Existing solutions lack adaptive control over thermal and moisture transport.

Purpose of the Study:

• To develop a stimuli-responsive smart textile for adaptive thermoregulation.
• To engineer a fabric capable of controlling infrared (IR) and water transmission.
• To create a textile that protects human skin from environmental changes.

Main Methods:

• Fabrication of a smart textile using shape memory polymer (SMP) fibers.
• Incorporation of hierarchical micro/nanoporous structures for thermal insulation.
• Coating one side with silver nanowires for asymmetric IR reflectivity and hydrophilicity.

Main Results:

• The SMP textile demonstrated tunable thermal insulation (65.7% control) and asymmetric wettability.
• Adaptive IR reflectivity was achieved, controlling surface temperature on a hot plate.
• Directional water droplet transport was switchable for effective sweat management.

Conclusions:

• The developed IR- and water-gating smart textile provides a novel strategy for skin protection.
• This technology offers adaptive thermoregulation by controlling heat and moisture.
• The smart textile shows promise for applications requiring dynamic environmental adaptation.
