The advent of more than half a meter of carbon nanotubes has taken an important step in the direction of application. The most important application of carbon nanotubes is the manufacture of strong, tough, light and cheap materials. Spider silk among natural materials is the toughest, and the toughness of carbon nanotube fibers exceeds that of spider silk. Such materials are extremely important in the aerospace field. In addition, carbon nanotubes also have unique structures and electrical conductivity, which can be used to make nano-scale electronic devices smaller and more sensitive than traditional electronic devices. However, general carbon nanotubes have different lengths, structural types and conductivity, and it is difficult to use them to produce devices with consistent structure and performance on a large scale. However, now The ultra-long carbon nanotubes overcome this problem and become a huge breakthrough.
