A World of Carbon Nanotubes Under a Powerful Microscope
Carbon nanotubes is composed of a single layer of graphite coaxial winding into tube (single-walled Carbon nanotubes) or by single-walled Carbon nanotubes along concentric layers of structure and set of tubes (multi-walled Carbon nanotubes), its in one to tens of nanometers in diameter, and length is far greater than its diameter, it is a kind of one-dimensional nanomaterials, Carbon has many superior physical properties (mechanical, electrical, thermal and chemical properties.
As the materials with the best mechanical properties ever discovered, carbon nanotubes have extremely high tensile strength, young's modulus and fracture strain. For example, specific strength (unit mass strength) is 270 times that of the highest strength steel (model ASTMA228), elasticity is about five times that of steel, and density is only one-sixth that of steel, which is significantly better than conventional carbon fiber. A series of new materials derived from carbon nanotubes have many excellent properties and are one of the most attractive fields of new materials in the future.
Let's take a look at the world of carbon nanotubes under a powerful microscope.
This is a high power microscope of a single carbon nanotube:

Carbon Nanotube Fiber (CNTF) is a macroscopic Fiber that twists and turns thousands of single nanotubes together. It has the characteristics of light weight, high strength and versatility. Carbon nanotubes are called the ultimate fibers. The carbon nanotube fibers formed through assembly have the characteristics of light weight, high strength and versatility, becoming a new generation of special fiber materials, which is of great strategic significance for the development of high-end science and technology in the 21st century.
