Multilayer Composites

Nano- and microstructured composite materials have opened a new era for multifunctional materials. In particular, barium hexaferrites and carbon nanotubes can be applied in order to improve electromagnetic properties in composites. Magnetic materials with a texture based on barium ferrite and carbon nanotubes were obtained. The electromagnetic properties of Z – hexaferrites / carbon nanotubes composites were measured at microwave frequencies. It was shown, that imaginary permeability of barium hexaferrites/carbon nanotubes multilayer composites with double texture is as much as that of an isotropic samples at regions 3.4 – 8.5 GHz and 7.1 – 11.6 GHz.

Parameters Calculation

In this paper electromagnetic properties of composite materials based on polymethylmethacrylate and multiwall carbon nanotubes (MWCNTs) are investigated. Carbon nanotubes are received with application of various types of catalysts and have various structural parameters. Calculation of dielectric permeability of the synthesised materials is carried out. Dependence of electromagnetic properties of composite materials on concentration and structure used multilayer carbon nanotubes is shown.

Walled Carbon Nanotubes

Hybrid composite materials based on an aluminium phosphate matrix with silicon carbide whiskers and multi-walled carbon nanotubes were studied in a wide frequency range (20 Hz to 36 GHz). It was demonstrated, that the addition of the silicon carbide whiskers enhances the dielectric permittivity and conductivity. This was explained by the difference in tunnelling parameters. Hybrid ceramics with nanotubes and whiskers also exhibits substantially improved electromagnetic shielding properties. The hybrid ceramics with 10 wt. % silicon carbide whiskers and a 1 mm thick 1.5 wt. % carbon nanotube layer, show higher than 50% absorption of electromagnetic radiation.
