Abstract
Nanotechnology is considered as the next major industrial revolution. It deals with materials at a molecular and atomic scale and is predicted that it will affect all aspects of our lives. Nano-materials are a major branch of nanotechnology that is characterized by different behaviors. One of the promising nano-materials that are expected to play an important role in industry is the carbon nanotubes (CNTs). The CNTs improve the efficiency of many tools, e.g., energy storage, electrical cables, and ultra-capacitors.
CNTs exhibit very different features under extreme conditions, such as high pressure. In addition, doping carbon nanotubes with nitrogen might enhance their performance and allows them for more advanced applications. In this study, we examined nitrogen-doped CNTs (CNX-NTS) under high pressure. We used 1.5% and 5.4% CNX-NTS samples that were exposed to pressure range up to 15 GPa. For both samples, there was no phase transformation. The two sample’s results suggest that doping of nitrogen strengthens the mechanical property of CNTs.
As the results showed, that CNX-NTS can overcome high-pressure rates (more than 15 GPa), and they can be used in applications that encompass high pressure. For example, in oil and gas industry, CNTs can be used in protecting oil and gas operation equipment and structures to provide protection, increase the service life, and decrease the maintenance cost.
