EMI Shielding Materials Used Multi-walled Carbon Nanotubes

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.
