Mechanically Robust, Responsive Composite Membrane for a Thermoregulating Textile

Area of Science:

• Materials Science
• Biomedical Engineering
• Textile Engineering

Background:

• Human body dissipates heat through conduction, convection, evaporation, and radiation.
• Elevated core body temperatures above 45°C can negatively impact metabolism and protein integrity.
• Effective personal microclimate control is crucial for thermal regulation and comfort.

Purpose of the Study:

• To develop an advanced fabric for effective personal microclimate control.
• To investigate a material with enhanced evaporative, radiative, and convective cooling properties.
• To create a comfortable and durable textile for heat release.

Main Methods:

• Fabrication of a thermo-moisture sensitive polyurethane/silica aerogel composite membrane.
• Integration of the membrane into a textile structure.
• Evaluation of the material's thermal properties, mechanical robustness, and air permeability.

Main Results:

• The developed fabric demonstrated super evaporative and radiative cooling effects.
• The material facilitated enhanced convection, aiding in heat dissipation.
• The textile exhibited robust mechanical properties, high water-evaporative ability, and good air permeability.

Conclusions:

• The novel fabric effectively controls the personal microclimate by promoting heat release.
• The developed material offers a promising solution for heat management in clothing.
• Microclimate-controlled textiles can significantly improve wearer comfort by facilitating body heat release.
