    Attenuation of electromagnetic waves by carbon nanotube composites
    (Amsterdam [u.a.] : Elsevier, 2008) Hornbostel, Björn; Leute, Ulrich; Pötschke, Petra; Kotz, Jochen; Kornfeld, Daniela; Chiu, Po-Wen; Roth, Siegmar
    Experiments on polycarbonate/single-walled carbon nanotube composites were performed to explore the potential of carbon nanotubes in attenuating electromagnetic waves. According to the results of these experiments a distinct effect is present. The effect is dependent on the tubular filler properties and on the morphology of the composite. At a loading of 5.4 wt% single-walled carbon nanotubes in polycarbonate an attenuation of the field of 47 dB could be detected, which corresponds an attenuation of the power of 99.998%.
