To enable highly conductive electronic textiles (E-textiles), we herein demonstrate a simple solution treatment of poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS)-coated textiles by dimethyl sulfoxide (DMSO) and methanol. The subsequent solution engineering of DMSO and methanol not only enhances crystallization of PEDOT chains but also the contact for PEDOT:PSS to the fibers. Additionally, the methanol dipping effectively removes the insulating PSS part from the conductive PEDOT chains, which contributes to subsequently reduced sheet resistance of less than 3 Ω/sq of the conductive textiles. Joule heating property of the highly conductive textiles achieves the maximum temperature with the temperature reaching 133 °C at a low applied voltage of 3 V within 20 s, which promises highly conductive E-textiles as multi-functional wearable heater applications.
为了实现高导电性的电子纺织品（E-纺织品），我们在此展示了一种通过二甲基亚砜（DMSO）和甲醇对聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）涂层纺织品进行简单溶液处理的方法。随后对DMSO和甲醇进行的溶液工程处理不仅增强了PEDOT链的结晶，还改善了PEDOT:PSS与纤维的接触。此外，甲醇浸渍有效地从导电PEDOT链中去除了绝缘的PSS部分，这有助于随后将导电纺织品的表面电阻降低至小于3Ω/□。高导电性纺织品的焦耳热性能在3V的低施加电压下20秒内达到最高温度133°C，这使得高导电性E-纺织品有望用于多功能可穿戴加热器应用。
