Durable, sensitive and wearable electronics are highly desirable for monitoring everything from vital signs to athletic performance. However, electronic textiles with excellent functions, stability, comfort, and durability against washing/rubbing remain a big challenge. Herein, a coating containing nanocomposites of polyaniline (PANI) with nanodiamond (ND) was applied to the surface of wool fabrics through an in situ polymerization technique. The nanocomposite fabrics with PANI-ND demonstrated high sensitivity, enhanced durability, and excellent mechanical properties without compromising the inherent properties of textiles such as comfort and breathability. Wool fabrics were treated with aniline, aniline-ND, and aniline-boron doped ND (BDND) to investigate the molecular interaction between ND/BDND and PANI and their effects on the final properties, such as comfort, mechanical and electrochemical properties of the treated fabric. The PANI-ND coated fabrics showed sheet resistances below 10 kΩ/sq and up to a 2-fold decrease in response to monotonically increasing and cyclic mechanical strains compared with the PANI-coated fabric. Wool fabric coated with PANI-ND is a sensitive sensor that can withstand strain up to 100%, which is remarkable for delicate fibers. The developed sensor can detect human motion, such as bending of a finger to different angles. The moisture properties of the fabric coated with PANI-ND improved significantly along with durability against washing and abrasion without affecting its breathability. This work provides insights into developing highly sensitive multifunctional electronic textiles (such as wearable sensors) without compromising the intrinsic properties of textiles.

纳米金刚石-聚苯胺纳米复合材料的多功能智能织物

耐用，灵敏和可穿戴的电子设备非常需要监视从生命体征到运动成绩的所有内容。然而，具有优异功能，稳定性，舒适性和耐洗涤/摩擦性的电子纺织品仍然是一个巨大的挑战。在本文中，含有聚苯胺（PANI）与纳米金刚石（ND）的纳米复合材料的涂层是通过施加到羊毛织物的表面原位聚合技术。具有PANI-ND的纳米复合材料织物表现出高灵敏度，增强的耐久性和出色的机械性能，而不会损害纺织品的固有性能，如舒适性和透气性。用苯胺，苯胺-ND和苯胺-硼掺杂的ND（BDND）处理羊毛织物，以研究ND / BDND和PANI之间的分子相互作用及其对最终性能的影响，例如处理后的舒适度，机械和电化学性能布。与PANI涂层的织物相比，PANI-ND涂层的织物表现出低于10kΩ/ sq的薄层电阻，并且响应于单调增加和周期性的机械应变而下降了2倍。涂有PANI-ND的羊毛织物是一种灵敏的传感器，可以承受高达100％的应变，这对于纤细的纤维而言非常出色。开发的传感器可以检测人的动作，例如手指弯曲到不同角度。涂有PANI-ND的织物的湿气特性以及耐洗涤和耐磨的耐久性均得到显着改善，而不会影响其透气性。这项工作为开发高度敏感的多功能电子纺织品（例如可穿戴传感器）提供了见识，而又不损害纺织品的固有特性。
