Silk has outstanding mechanical properties and biocompatibility. It has been used to fabricate traditional textiles for thousands of years and can be produced in large scale. Silk materials are potentially attractive in modern textile electronics. However, silk is not electrically conductive, thus limiting its applications in electronics. Moreover, regenerated silk is generally rigid and brittle, which hinder post processing. Here we report the fabrication of conductive silk wire in which carbon nanotube (CNT) yarns are wrapped with fluffy and flexible silk nanofiber films. The silk nanofiber film was prepared by electrospinning and then wrapped around a rotating CNT yarn in situ. The obtained silk-sheathed CNT ([email protected]) wire has an insulating sheath, which protects the body against electrical shock. In addition, the fabricated wires exhibit a high electrical conductivity (3.1 × 104 S/m), good mechanical strength (16 cN/tex), excellent flexibility, and high durability. More importantly, the wires have an extremely low density (2.0–7.8 × 104 g/m3), which is 2 orders of magnitude lower than that of the traditional metal wire (for example, Cu). Moreover, the wires display a good resistance to humidity, and a simple post treatment can make the wires splash-resistant, thereby expanding its applications. On the basis of these features, we demonstrate the use of the lightweight [email protected] wires in smart clothes, including electrochromism and near-field communication.

纺织电子用防溅轻量丝套线
丝绸具有出色的机械性能和生物相容性。它已经被用于制造传统纺织品数千年，并且可以大规模生产。丝绸材料在现代纺织电子领域具有潜在的吸引力。但是，蚕丝不导电，因此限制了其在电子领域的应用。而且，再生的丝通常是硬而脆的，这阻碍了后加工。在这里，我们报告了导电丝线的制造，其中碳纳米管（CNT）纱线被蓬松而柔软的丝纳米纤维膜包裹着。通过静电纺丝制备丝纳米纤维膜，然后将其原位包裹在旋转的CNT纱线周围。所获得的带有丝鞘的CNT（[受电子邮件保护]）线具有绝缘护套，可以保护人体免受电击。此外，4 S / m），良好的机械强度（16 cN / tex），出色的柔韧性和高耐久性。更重要的是，导线的密度极低（2.0–7.8×10 4 g / m3），比传统金属线（例如Cu）的密度低2个数量级。此外，电线表现出良好的耐湿性，并且简单的后处理可以使电线具有防飞溅性，从而扩展了其应用范围。基于这些功能，我们演示了在智能衣服中使用轻型[受电子邮件保护]的电线，包括电致变色和近场通信。
