AI Article Synopsis
- Stabilization techniques for n-doped carbon nanotubes (CNTs) are crucial for the functionality of CNT devices, but existing n-dopants lack durability in real-world settings.
- A new method is introduced that enhances air stability of n-doped CNT films by fully encasing them in n-dopants, although exposure to scratches or moisture can compromise this stability.
- The study also highlights the use of parylene as a protective layer, achieving over a year of air stability, while demonstrating superior thermo-electric power generation capabilities compared to traditional n-dopants, paving the way for broader applications of CNT technology.
Article Abstract
Stabilization techniques for n-doped carbon nanotubes (CNTs) are essential for the practical use of CNT devices. However, none of the reported n-dopants have sufficient robustness in a practical environment. Herein, we report a highly stable technique for fabricating n-doped CNT films. We elucidate the mechanism by which air stability can be achieved by completely covering CNTs with n-dopants to prevent oxidation; consequently, the stability is lost when exposed to scratches or moisture. Therefore, we introduce parylene as a protective layer for n-doped CNTs and achieve air stability for more than 365 d. Moreover, we demonstrate outstanding robust thermo-electric power generation from strong acids, alkalis, and alcohols, which cannot be realized with conventional air-stable n-dopants. The proposed stabilization technique is versatile and can be applied to various n-dopants. Thus, it is expected to be a key technology in the practical application of CNT devices.
