Description

technical field [0001] The invention relates to the technical field of carbon nanotube purification, in particular to a device and method for directly electrifying and purifying carbon nanotubes. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes have excellent physical and mechanical properties. They are mainly coaxial circular tubes with several to dozens of layers of carbon atoms arranged in a hexagonal shape. It has a very large aspect ratio, the diameter is usually between 1-100nm, and the length is several microns to hundreds of microns. It is precisely because of its sP2 structure and huge aspect ratio that carbon nanotubes perform very well in terms of mechanics, electricity, and electrical and thermal conductivity. Due to its excellent properties, carbon nanotubes have broad and potential application prospects in many fields such as catalyst supports, rubber-plastic composite materials, electrochemical materials, and photoelectric sen...
