Title
Wash-Durable Conductive Yarn with Ethylene Glycol-Treated PEDOT:PSS for Wearable Electric Heaters
Abstract
Recently, wearable electric heaters with high durability and low-power operation have attracted much attention due to their potential to change traditional approaches for personal heating management and thermal therapy systems. Here, we report textile-based wearable heaters based on highly durable conductive yarns, which were transformed from traditional cotton yarns through a facile dyeing process of poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) and ethylene glycol (EG). With the EG post-treatment, the conductive yarns exhibited an electrical conductivity of ∼76 S cm-1 and good stability under repeated cycles of washing and drying. The heating elements made from the conductive yarns showed an excellent distribution of temperature and could be heated up to 150 °C at a sufficiently low driving voltage of 5 V. Also, the heating elements showed stable Joule heating performance under repeated bending stress and 2000 cycles of stretching and releasing. To demonstrate its practical use for on-body heating systems, a lightweight and air-breathable thermal wristband was demonstrated by sewing the conductive yarns onto a fabric with a simple circuit structure. From these results, we believe that our strategy to obtain highly conductive and durable yarns can be utilized in various applications, including medical heat therapy and personal heating management systems.
