Electromagnetic properties of composites containing graphite nanoplatelets at radio frequency

The effect of three different carbon-based nano and microfillers on the electromagnetic (EM) performance of polymeric composites was examined through the measurement of the effective complex permittivity in the frequency range from 8.2 to 18 GHz. Results show that polymeric composites based on graphene nanoplatelets are much more easily processable than composites filled with carbon nanotubes, while still retaining much of the EM performance over the investigated frequency band, as well as being light weight.
