最近，人们对满足现代社会技术需求的轻质、柔性和可穿戴电子产品产生了浓厚的兴趣。这种类型的集成储能设备是一个仍显着不发达的关键领域。在这里，我们描述了使用日常纺织品作为平台的可穿戴电力设备。通过使用单壁碳纳米管（SWNT）油墨的极其简单的“浸渍和干燥”工艺，我们生产出了电导率为125 S cm（-1）、薄层电阻小于1 Ω/sq的高导电纺织品。这种导电织物显示出出色的柔韧性和可拉伸性，并证明了SWNT和感兴趣的织物之间的强粘附性。由这些导电纺织品制成的超级电容器显示出高达0.48F/cm（2）的高面电容和高比能量。我们证明了将伪电容器材料加载到这些导电纺织品中，导致设备的面积电容增加24倍。这些高导电纺织品可以为可穿戴电子产品和储能应用提供新的设计机会。
Recently there is strong interest in lightweight, flexible, and wearable electronics to meet the technological demands of modern society. Integrated energy storage devices of this type are a key area that is still significantly underdeveloped. Here, we describe wearable power devices using everyday textiles as the platform. With an extremely simple "dipping and drying" process using single-walled carbon nanotube (SWNT) ink, we produced highly conductive textiles with conductivity of 125 S cm(-1) and sheet resistance less than 1 Omega/sq. Such conductive textiles show outstanding flexibility and stretchability and demonstrate strong adhesion between the SWNTs and the textiles of interest. Supercapacitors made from these conductive textiles show high areal capacitance, up to 0.48F/cm(2), and high specific energy. We demonstrate the loading of pseudocapacitor materials into these conductive textiles that leads to a 24-fold increase of the areal capacitance of the device. These highly conductive textiles can provide new design opportunities for wearable electronics and energy storage applications.
