Area of Science:

• Materials Science
• Textile Engineering
• Nanotechnology

Background:

• Textile-based electronics offer solutions for thermal management, therapy, and deicing via Joule heating.
• Challenges exist in creating cost-effective and efficient flexible heating devices.

Purpose of the Study:

• To develop a high-performance, cost-effective Joule heating device using intrinsically conducting polymers on textiles.
• To investigate the electrothermal properties and stability of the fabricated textile heater.

Main Methods:

• A facile solution-processed dip-coating strategy was employed.
• Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) was uniformly coated onto cotton textiles.
• Structural, morphological, and electrothermal characteristics were evaluated.

Main Results:

• The cotton/PEDOT:PSS composite exhibited rapid thermal response and uniform temperature distribution up to 94 °C.
• The device demonstrated excellent stability and endurance under mechanical deformation.
• Real-time application on a human finger showcased potential for thermal therapy.

Conclusions:

• The dip-coated PEDOT:PSS on cotton textiles presents a promising high-performance Joule heating device.
• The fabricated fabric heater has significant potential for thermal therapy, deicing, defogging, and defrosting applications.
