Electronic textiles (e-textile) have emerged as a new generation of wearable electronics. Although carbon nanotube (CNT) based e-textiles have drawn tremendous attention, a big concern is the washability of these e-textiles. Here, we describe a novel and facile method to fabricate e-textiles by ultrasonic soldering of CNTs on low cost and eco-friendly non-woven fabric (NWF). When a piece of NWF is subjected to ultrasonication in a CNT dispersion, the NWF can be locally softened so that CNTs can be soldered on the fiber surface and lead to conductive textiles. The ultrasonic nanosoldering of CNTs onto the polymer surface is attributed to the huge pressure and high temperature produced by the collapsing of bubbles during ultrasonication. The CNT e-textiles fabricated by this method have good washability. The CNTs remain on the fiber surface even after vigorous mechanical washing in water for 40 hours, and the conductance of the textile decreases slightly, and the change arises from the damage of NWF fibers rather than the rinsing away of the CNTs. The e-textiles can be used as wearable strain and pressure sensors. They can be used for healthcare applications such as monitoring the blood pulse and respiration rate of the human body.

通过将碳纳米管超声纳米焊接到聚合物纤维上而制备的高度可洗的电子纺织材料†

电子纺织品（电子纺织）已经成为新一代的可穿戴电子产品。尽管基于碳纳米管（CNT）的电子纺织品引起了极大的关注，但人们最关心的是这些电子纺织品的可洗性。在这里，我们描述了一种新颖，简便的方法，该方法通过在低成本且环保的无纺布（NWF）上超声焊接CNT来制造电子纺织品。当一块NWF在CNT分散液中进行超声处理时，NWF可以局部软化，从而CNT可以焊接在纤维表面上并形成导电纺织品。CNT在聚合物表面上的超声纳米焊接归因于超声过程中气泡的破裂所产生的巨大压力和高温。通过这种方法制造的CNT电子织物具有良好的可洗性。即使在水中进行了强力的机械洗涤40小时后，CNT仍保留在纤维表面上，纺织品的电导率略有下降，并且这种变化是由NWF纤维的损坏引起的，而不是由CNT的漂洗引起的。电子纺织品可用作可穿戴的应变和压力传感器。它们可用于医疗保健应用，例如监测人体的脉搏和呼吸频率。
