Preparation and electromagnetic and microwave absorbing properties of Fe-filled carbon nanotubes

High temperature electromagnetic and microwave absorbing properties of polyimide/multi-walled carbon nanotubes nancomposites

“…However, most studies in literature on absorbing materials were performed in polyaniline [11], epoxy [12], polyamide resins [13], nature rubber [14] and so on [15], and those polymeric matrix could not use at elevated temperature due to their low thermal stability, therefore choose a kind of high heat resistance polymer is needed. Penylethynyl terminated polyimides, which account for many high performance polymer systems, are noted for their thermo-oxidative stability, high wear resistance, excellent electrical properties and high mechanical properties [16,17].…”

Microstructure and electromagnetic characteristics of Ni nanoparticle film coated carbon microcoils

“…Perfect microwave absorbers can be obtained by optimizing the dielectric and magnetic properties of a material such as its complex permittivity and permeability [25]. In order to investigate the ability of the uncoated and coated CMCs to absorb microwaves, we have measured and compared their complex permittivity and permeability in the frequency range 8.2-12.4 GHz.…”

Quantitative detection of carbon nanotubes in biological samples by an original method based on microwave permittivity measurements

“…They feature notably high shielding properties against electromagnetic (EM) interference (dissipation of the incident EM radiation as heat) [19], which make CNTs good candidates for the development of composite materials suitable for industrial EM applications (for example microwave absorption devices). They are generally incorporated in polymers, such as epoxy resins, [20][21][22][23][24], to design materials with improved electronic, thermal and mechanical properties compared with their components. The electrical properties of CNTs are often studied through their complex permittivity determined from transmission and/or reflection measurements in microwave range [20,24].…”
