Product Name
Name: High Quality carbon nanotube 8-20nm
Product Overview
Multi-walled carbon nanotubes (MWCNTs) are important nanomaterials with unique structures and excellent properties. Multi-walled carbon nanotubes are hollow tubules composed of multiple coaxial graphite cylindrical surfaces, and the spacing between adjacent cylindrical surfaces is comparable to the spacing of graphite layers. Multi-walled carbon nanotubes can be seen as coaxially nested with multiple single-walled carbon nanotubes of different diameters, with the number of layers ranging from 2 to 50, and the spacing between each layer is consistent, forming a cable-like multilayer structure. At present, the preparation methods of multi-walled carbon nanotubes mainly include arc discharge method, laser ablation method, chemical vapor deposition (CVD) method and flame method. Among them, the chemical vapor deposition method is widely used because of its simple equipment and high product purity.
