    Development History of Carbon Nanotubes

    Carbon nanotubes are one-dimensional quantum materials with unique structures (radial dimensions are on the order of nanometers, axial dimensions are on the order of micrometers, and the ends of the tube are sealed). Carbon nanotubes are mainly coaxial tubes composed of carbon atoms arranged in hexagons, ranging from several layers to tens of layers. A fixed distance is maintained between the sheets, about 0.34 nm, and the diameter is generally 2-20 nm. And according to the different orientations of the carbon hexagon in the axial direction, it can be divided into three types: zigzag, armchair, and spiral. Carbon nanotubes, as one-dimensional nanomaterials, are lightweight and have a hexagonal structure with perfect connections. They have many unusual mechanical, electrical, and chemical properties.

    Is Graphite Powder Dangerous

    Graphite powder itself is no harm. Still, for a long time in the graphite powder environment, you need to pay attention to because the graphite powder particles are tiny, graphite dust will enter the lungs through the human respiratory tract, which will cause harm to the human body. It is protected by wearing a wet mask. Graphite powder and oil mixed graphite oil in the high temperature will only have a pungent smell, as long as the protection, protection measures in place will not cause harm to the human body.

    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.
