Abstract

Recent advances in transparent wearable electronics highlighted the need for flexible conductive layers with high transmittance. Carbon nanotubes (CNTs) are ideal candidates for constructing transparent conductive networks due to their excellent flexibility, desirable optical properties, and outstanding electrical characteristics. However, their performance is severely degraded by the junction resistance between individual CNTs. Herein, we prepared nearly invisible and transferable ultralong CNT conductive networks with high transmittance (>99% at 550 nm). The centimeter-scale length of ultralong CNTs facilitated the successful assembly of conductive and suspended networks with a minimal thickness, absorption area, and junction density, enabling ultrahigh transmittance and transferability. Further, we developed an ultralong CNT-based flexible and transparent pressure sensor to verify their practical value. The sensor exhibited a high sensitivity (225.11 kPa–1), a broad operating range (up to 160 kPa), a rapid response time (11 ms), and robust stability over 10,000 cycles, outperforming most state-of-the-art transparent pressure sensors. This work shows the promising application potential of ultralong CNTs in high-performance transparent wearable electronics.

用于透明可穿戴电子设备的高透明可转移超长碳纳米管网络
透明可穿戴电子设备的最新进展凸显了对具有高透光率的柔性导电层的需求。碳纳米管(CNT)具有极佳的柔韧性、理想的光学特性和出色的电气特性,是构建透明导电网络的理想候选材料。然而,单个碳纳米管之间的结电阻严重降低了它们的性能。在此,我们制备了几乎不可见且可转移的超长 CNT 导电网络,其透光率高达 99%(550 纳米波长)。超长 CNT 的厘米级长度有助于成功组装厚度、吸收面积和结点密度极小的导电悬浮网络,从而实现超高透射率和可转移性。此外,我们还开发了一种基于超长碳纳米管的柔性透明压力传感器,以验证其实用价值。该传感器具有灵敏度高(225.11 kPa-1)、工作范围广(高达 160 kPa)、响应时间快(11 ms)、稳定性强(超过 10,000 次循环)等特点,优于大多数最先进的透明压力传感器。这项工作表明,超长碳纳米管在高性能透明可穿戴电子设备中具有广阔的应用前景。
