Application for MWCNTs:
1. EMI shielding materials and invisible
material. Because of the special structure and dielectric properties of carbon
nanotubes showed strong broadband microwave absorption properties, it also has
a light weight, adjustable conductivity change, strong oxidation resistance and
good stability, is a promising ideal microwave absorber, can be used for stealth
materials, electromagnetic shielding materials or darkroom absorbing materials.
2. The carbon nanotubes will be used for
the manufacture and absorption of electromagnetic shielding material has
stealth capabilities electromagnetic interference. Carbon Nanotubes for
infrared and electromagnetic stealth action for two main reasons: one nanometer
particle size is much smaller than the wavelength of infrared and radar, and
therefore such material nanoparticles wave transmittance to be much stronger
than conventional materials, which greatly reduces the reflectivity of waves,
such that the infrared detector and radar received reflected signal becomes
very weak, so as to achieve the role of stealth; on the other hand, the
specific surface area than conventional materials nanoparticles large meal 3 ~
4 orders of magnitude , infrared light and electromagnetic wave absorption rate
is much greater than conventional materials, which makes greatly reduces the
intensity of the infrared detector and the reflected radar signals obtained, it
is difficult to find the target to be detected, played a role in stealth. Since
the electromagnetic wave transmitted to the surface of the material is
absorbed, no reflection, thus to achieve invisibility.
