Carbon nanotubes are divided into different types according to different standards. Carbon nanotubes are formed after the graphene sheets are curled. Therefore, if we divide them according to the number of layers of graphene sheets, we can divide them into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types.
What are the classification of Carbon Nanotubes? Carbon nanotubes are composed of several layers of hexagonal carbon atoms. The Axis size is only micrometer, the two ends are closed, and the radial size is only nanometer, according to the difference of carbon six-side type along the axis direction in the industry, carbon nanotubes are classified as follows, namely, Sawtooth carbon nanotubes, armchair carbon nanotubes and spiral carbon nanotubes.
Carbon simple crystal, far infrared emission paper shows a new heating mechanism. Different from traditional heating, it first heats itself and then conducts heat through temperature difference. After we electrify the far infrared transmitting paper, the whisker carbon nanotubes in it will have friction, oscillation, drift and other activities in the nanometer level, and generate electromagnetic waves, the so-called phonon oscillation generates heat. Phonon energy is transmitted in the form of far infrared, without internal phonon scattering loss, the object can be heated quickly.
