Electromagnetic wave absorbing properties of carbon nanotubes doped rare metal/pure carbon nanotubes double-layer polymer composites

The design of double-layer structure could improve the absorbing properties of electromagnetic (EM) wave absorbing composites. Doping of rare metal (RM) could enhance the EM wave absorbing capability of the multi-walled carbon nanotubes (MWCNTs). In this paper, the polymer matrix composites with the different RM-doped MWCNTs and the pure MWCNTs as the absorber in the first and second layer respectively was fabricated (4 mm in thickness). The EM...
