  Poly(3,4-ethylenedioxythiophene) (PEDOT) is synthesized from 3,4-ethylenedioxythiophene (EDOT) as a conductive polymer material with many excellent properties such as high electrical conductivity and good stability. It has been widely used in many fields. In particular, its stretchability has made flexible electrode technology and wearable devices become an emerging research hot spot in recent years. Recently, a research team from the University of Massachusetts at Amherst developed an electric heating cloth using PEDOT [1] which can keep people warm in cold weather.
  The researcher's raw material is a pair of ordinary gloves, the glove fingers were coated with a layer of 1.5μm thick PEDOT film by vapor deposition method. The hand feel, weight, and breathability of the textiles after the coating process are imperceptible. The sheet resistance reached 44Ω/□ on the fabric and 61Ω/□ on the cotton fabric. Then a 1.8g coin battery was used to power the glove. A small amount of current will flow through the fabric, and the glove will continue to heat up, and the temperature will not be too high to damage the skin.
  In the test, the use of the coin cell battery glove can maintain a temperature of about 8 hours, but if you use the rechargeable battery, the using time can be extended. In addition, the biggest advantage of this glove is that it can still work after torn, repaired and even immersed in water, which means that it will not affect the use of gloves, whether it is snow or rain. Because of the high curvature of the fabric at the finger, this is enough to prove that the heatable cloth made of PEDOT is very flexible. In addition to the gloves, the researchers also tried on the sweater, and obtained good results, which indicated that this coating method can be used for a variety of clothing.
  Heatable cloth will provide people with a steady stream of heat, and perhaps soon, people do not have to wear cotton in the winter. All along, people are pursuing lightweight, breathable, long lasting heat source, and high comfort electric heating equipment, electric heating cloth is not only convenient for our daily life, it may also provide convenience for other areas such as medical rehabilitation treatment in the future..
