Carbon nanotubes

Product Introduction

As one-dimensional nanomaterials, carbon nanotubes has many mechanical, electrical and chemical properties with light weight and perfect hexagonal connection structure.In recent years, with the further research of carbon nanotubes and nanomaterials, continuously show its broad application prospects.Carbon nanotubes, also known as bakelite, are one-dimensional quantum materials with special structure (radial size is nanometer, axial size is micron, both ends of the tube are basically sealed). It keeps a fixed distance between layers, about 0.34 nm, and the diameter is generally 2~20 nm. According to different axial orientation of carbon hexagon, it can be divided into three types: sawtooth, armchair and spiral shape. Among them, spiral shape carbon nanotubes have chirality, while sawtooth and armchair shape carbon nanotubes have no chirality.
