Nanostructured composite layers for electromagnetic shielding in the GHz frequency range

- Paint-like nanocomposite layers consisting of graphene nanoplatelets, PANI:HCl and PEDOT:PSS present very effective attenuation of electromagnetic radiation in the frequency range 4-20 GHz.
- The shielding performance is based mostly on the graphene nanoplatelets and supported by PANI:HCl. In contrast, PEDOT:PSS plays mainly the role of the binder.
- Increasing resistivity was observed to reduce the shielding effect, while increasing thickness to favor it.
