Refers to carbon nanotubes. In carbon nanotubes, also known as Bucky pipe, is a one -dimensional quantum material with a special structure (radial size is nano -level, axial size is micronweight, and the ends of the tube is basically sealed). Essence Carbon nanotubes are mainly composed of carbon atoms arranged in hexagonal formation to dozens of coaxial tubes from dozens of layers. A fixed distance between layers and layers, about 0.34nm, generally 2 ~ 20nm. The discovery history:
before the carbon nanotubes were officially recognized and named in 1991, it was found and manufactured in some studies, but it was not realized at the time that it was a new kind of new one. Important carbon form. In 1890, it was found that carbon -containing gas can decompose to form silk carbon on the surface. In 1953, when CO and Fe3O4 reacted at a high temperature, it was also found that the silk -like structure similar to carbon nanotubes was also found. Since the 1950s, the problem of carbon accumulation of petrochemical plants and cold -nuclear reactors, that is, the problem of carbon silk accumulation, gradually attracted attention. In order to curb its growth, many research on its growth mechanism was carried out. The carbon silk obtained by organic matter catalytic heat solution has been found in the structure of carbon nanotubes similar to carbon silk. In the late 1970s, when New Zealand scientists found that when two graphite electrodes were powered on to generate electric sparks, small fiber clusters were generated on the surface of the electrode. In fact, multi -wall carbon nanotubes have been observed.
