Carbon nanotubes (MWNTs) have closed due to the planar π electron system, large specific surface area and the surface is rich in pore structure as an ideal gas adsorbent and hydrogen storage material [1] is expected to energy and environmental sustainability development of solution. compared with conventional gas-sensitive materials, carbon nanotubes with high sensitivity, low test temperature characteristics, so people use in recent years has a strong affinity between the gas molecules and the ability of carbon nanotubes, and the adsorption belong single molecule adsorption characteristics of highly dispersed carbon nanotubes into nanoscale gas sensor. electrical properties of semiconductor-type carbon nanotubes showed reducing gas NO, CO and oxidized gas O2, NO2 adsorbed on carbon, etc. the nanotubes, the electrical properties of carbon nanotubes can change dramatically. this is due to electron transfer between the gas and the carbon nanotubes, so the carrier density of the semiconductor carbon nanotubes changed.

Carbon Nanotubes (CNT) has excellent mechanical, thermal, electrical and other physical and chemical properties, which are widely used in polymer composite material modification, since larger aspect ratio, just add little CNT, can significantly improve the polymer matrix performance.
