Electronic textile (E-textile) with excellent electrical/mechanical properties in large area is an essential component for wearable electronics. We herein demonstrated that brush-painting is a promising printing technique of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on fabric substrates to prepare ultra-flexible, stretchable, and highly conductive E-textiles. The brush-painting allows uniform film surface with much lower sheet resistance which is opposite to agglomerated particulates of the film from the drop-casting. As a result, the PEDOT:PSS-based E-textiles achieve high conductivity of 6.4 S cm⁻¹ after successive bush-painting up to 50 times with excellent mechanical properties including bending, stretching, and washing stability. The brush-painted E-textiles exhibit excellent Joule heating properties with low operative voltage and quick response time. In addition, the large-area piezoresistive sensors have been realized by the brush-painted E-textiles, suggesting its great potential of the brush-painting PEDOT:PSS toward multi-functional smart textiles or wearable electronics.

大面积具有优异电气/机械性能的电子纺织品（E-textile）是可穿戴电子产品的重要组成部分。我们在此证明了刷涂是一种很有前途的聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）印刷技术，用于在织物基材上制备超柔韧、可拉伸和高导电性的电子纺织品。刷涂允许具有低得多的薄层电阻的均匀膜表面，这与来自滴铸的膜的附聚颗粒相反。因此，基于 PEDOT:PSS 的电子纺织品实现了 6.4 S cm ^{-1 的}高电导率连续刷漆 50 次后，具有优异的机械性能，包括弯曲、拉伸和洗涤稳定性。刷涂电子纺织品具有出色的焦耳加热特性，操作电压低，响应时间快。此外，大面积压阻传感器已通过刷漆电子纺织品实现，表明其刷漆PEDOT：PSS在多功能智能纺织品或可穿戴电子产品方面的巨大潜力。
