Application of multi walled carbon nanotubes:

Carbon nanotubes (MWNTs) are closed due to the planar π electron system, with a large specific surface area and rich pore structure on the surface. They are an ideal gas adsorbent and hydrogen storage material [1], and are expected to be the sustainable development of energy and the environment. provide the solution. Compared with traditional gas-sensitive materials, carbon nanotubes have the characteristics of high sensitivity and low test temperature. Therefore, in recent years, people have used the ability between gas molecules with strong affinity and carbon nanotubes, and the adsorption is a single molecule adsorption. The height characteristics of the carbon nanotubes are dispersed into the nano-scale gas sensor. The electrical properties of semiconductor-type carbon nanotubes are shown as reducing gases NO, CO and oxidizing gases O2, NO2 is adsorbed on carbon and so on. The electrical properties of nanotubes and carbon nanotubes will change dramatically. This is due to the electron transfer between the gas and the carbon nanotubes, so the carrier density of the semiconductor carbon nanotubes has changed.

Carbon nanotubes (CNT) have excellent mechanical, thermal, electrical, and other physical and chemical properties. Due to the large aspect ratio, only a small amount of CNT can be added to significantly improve the performance of the polymer matrix, so it is widely used in polymers Modification of composite materials.
