This study introduces a novel smart textile for personal thermal management, offering enhanced heating and multiple functionalities. The advanced fabric provides superior warmth, self-cleaning, and protection, paving the way for next-generation warming textiles.
Area of Science:
- Materials Science
- Textile Engineering
- Nanotechnology
Background:
- Developing smart textiles for personal thermal management (PTM) is crucial for human comfort in cold environments.
- Existing PTM textiles face limitations in thermal conversion efficiency, energy sources, and functional versatility.
Purpose of the Study:
- To design and demonstrate an asymmetrically structured PTM textile with enhanced photothermal and electrothermal conversion capabilities.
- To integrate self-cleaning, electromagnetic shielding, and antimicrobial properties into a single smart textile.
Main Methods:
- A multi-energy-coupled textile was engineered using a self-polymerization method and vacuum filtration.
- The design incorporates a micronano rough structure of polyaniline and polypyrrole (PANI-PPY) and silver nanowires (AgNWs) coating.
- Polydimethylsiloxane (PDMS) encapsulation was utilized for enhanced properties.
Main Results:
- The textile achieved high solar absorption (98.4%) and mid-infrared reflectance (70.1%).
- Demonstrated superior solar heating (80.6 °C) and Joule heating (144 °C) capabilities.
- Exhibited excellent self-cleaning (water contact angle: 153.3°), electromagnetic shielding (76.12 dB), and antimicrobial (100%) properties.
Conclusions:
- The developed asymmetric PTM textile offers superior thermal comfort and multi-functionality.
- This research provides a foundation for creating advanced warming textiles with integrated features.
- The findings suggest potential for next-generation smart fabrics in personal thermal management applications.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...
