Carbon nanotubes are a promising material for flexible/wearable electrochemical device due to their mechanical softness, chemical stability, and high conductivity. Furthermore, the vertically aligned form of carbon nanotubes (VACNTs) have a large surface area due to their unique three‐dimensional (3D) nanostructure. Thus, VACNTs are particularly useful for wearable electrochemical sensors and/or energy devices. However, VACNTs are generally grown via a high‐temperature chemical vapor deposition process, which requires a rigid substrate. As a flexible/wearable device platform, therefore, VACNTs should be transferred from rigid substrates to soft substrates. Here, a facile fabrication and transfer method of a unique 3D nanostructure, that is, VACNTs on the Mo/Ni bilayer, for high performance flexible/wearable devices is reported. After growth of VACNTs on a Mo/Ni bilayer, VACNTs with the Mo/Ni bilayer can be easily peeled‐off from the SiO₂ wafer by using weak adhesion of Ni to SiO₂ for transfer printing onto polymeric/elastomeric substrates. Moreover, the Mo layer helps facile growth of VACNTs, and the Mo/Ni bilayer underneath VACNTs maximizes the lateral current flow. The proposed 3D nanostructure (VACNTs on the Mo/Ni bilayer) is successfully applied as flexible electrodes for high‐performance wearable asymmetric supercapacitors.

Mo / Ni双层可穿戴能源设备上垂直排列的碳纳米管的简便制造和转移方法

碳纳米管由于其机械柔软性，化学稳定性和高导电性，是用于柔性/可穿戴电化学装置的有前途的材料。此外，由于其独特的三维（3D）纳米结构，碳纳米管（VACNT）的垂直排列形式具有较大的表面积。因此，VACNT对于可穿戴电化学传感器和/或能量装置特别有用。但是，VACNT通常是通过高温化学气相沉积工艺生长的，这需要坚固的基材。因此，作为柔性/可穿戴设备平台，VACNT应该从刚性基材转移到软质基材。在此，报告了一种用于高性能柔性/可穿戴设备的独特3D纳米结构（即Mo / Ni双层上的VACNT）的便捷制造和转移方法。通过使用Ni对SiO _2的弱粘附力将图_2的晶片转移到聚合物/弹性体基底上。此外，Mo层有助于VACNTs的轻松生长，而VACNTs下方的Mo / Ni双层可使横向电流最大化。拟议的3D纳米结构（Mo / Ni双层上的VACNTs）已成功地用作柔性电极，用于高性能可穿戴非对称超级电容器。
