Study on the Electromagnetic-Protective Specialty of Carbon Nanotubes

Abstract:

Based on electromagnetic-wave penetration method, the electromagnetic wave attenuation abilities of six kinds of CNTs were studied in experiment at 12~18 GHz, whose diameter at 30 nm, 60 nm, 100 nm and length at 2 μm and 15 μm. Such results are concluded from the experiment. With the same diameter 30 nm, the absorption ability of CNTs with the length 15 μm is better than which with the length 2 μm; With the same diameter 60 nm, the absorption ability of CNTs with the length 2 μm is better than which with the length 15 μm; With the same diameter 100 nm, electromagnetic attenuation ability of CNTs with the length 15 μm is better than which with the length 2 μm. Electromagnetic attenuation ability order of CNTs with the same length is that Ф60 nm > Ф100 nm > Ф30 nm. On the absorption ability, the best is CNTs with Ф60 nm × 2 μm, and the worst is CNTs with Ф30 nm × 2 μm. At 12~18 GHz, the absorption orders of the six kinds of CNTs is that Ф60 nm × 2 μm > Ф 60 nm × 15 μm > Ф100 nm × 15 μm >Ф100 nm × 2 μm > Ф 30 nm × 15 μm > Ф 30 nm × 2 μm.
