Product Overview
Carbon nanotubes are simple substances composed of carbon atoms and can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, the carbon atoms are bonded to each other in the form of sp2 hybrid orbitals, which are arranged as hexagonal graphite layers. In theory, this regular hexagonal structure is perfectly evenly distributed over the entire surface of the carbon nanotubes. Topologically, the common structure and properties of graphene and carbon nanotubes are one of the important factors for their similarity. However, due to the curvature of the graphite layer in the carbon nanotubes, coupled with the defects that may occur during the growth process, the sp3 hybrid phenomenon may occur in the six-membered ring structure on the surface of the carbon nanotubes, resulting in the emergence of five-membered rings or seven-membered rings. Carbon nanotubes can be divided into single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes according to the graphite sheets with different number of layers.
There are many kinds of preparation processes and methods for carbon nanotubes, and carbon nanotubes with corresponding properties and structures can be prepared by different methods. At present, the main methods for preparing carbon nanotubes include graphite arc method, laser graphite evaporation method and chemical deposition method. Chemical deposition method has the advantage of large-scale production and is widely used at present.
