| Message: | 1.Shenzhen Topology Precision Film Technology Co., Ltd. are one of the leading Nano manufacturer in China. The introduction of company is following:5.Before the carbon nanotube was officially recognized and named in 1991, it was discovered and manufactured in some studies, but it was not recognized at the time that it was a new and important form of carbon. In 1890, it was discovered that carbon-containing gases decomposed on hot surfaces to form filamentous carbon. In 1953, when carbon and Fe3O4 reacted at high temperature, a filamentous structure similar to carbon nanotube was also found. Since the 1950s, the problem of carbon deposition in petrochemical plants and cold nuclear reactors, that is, the problem of carbon filament accumulation, has gradually attracted attention. In order to suppress its growth, many researches on its growth mechanism have been carried out. Carbon nanotube-like structures have been found in these carbon filaments obtained by catalytic pyrolysis of organic matter. In the late 1970s, New Zealand scientists discovered that when an electric spark was generated between two graphite electrodes, small fiber clusters were formed on the surface of the electrode. Electron diffraction measurements revealed that the walls were composed of graphite-like carbon, which was actually observed. To multi-wall carbon nanotubes. The carbon atoms in the carbon nanotube are mainly sp2 hybrid, and the hexagonal mesh structure has a certain degree of curvature, forming a spatial topology..Shenzhen Topology Precision Film Technology Co., Ltd. has over 10 years experience to export our products to almost all over the world. Our main market is North America,East Asia, and we still constantly expanding new markets.x318b6dan
