| Popis: | Radio-absorbing properties of polymer composite materials with carbon nanotubes (CNT) are studied in the extremely high frequency (EHF) range. The possibility is shown of producing radio-absorbing materials (RAMs) with CNT efficiently absorbing electromagnetic radiation (EMR) in the range of 52–73 GHz at thicknesses 15–30 times smaller as compared with materials containing traditional fillers, such as technical carbon and graphite. It is shown that absorbing properties analogous to the materials containing traditional fillers are reached by composites with CNTs at a significantly lower reflection coefficient on the interface boundary. An advantage of RAM fabrication using mechanical mixing as compared to ultrasonic treatment is considered. |
