Abstract :
Novel graphene-based nanocomposites, consisting of a polymeric-based system filled with graphenenanoplatelets (GNP), are developed for application as low-cost lightweight electromagnetic shielding materials. High concentration and good dispersion of the GNPs inside a thermosetting polymeric matrix is achieved in order to enhance the shielding properties of the nanocomposite through the control of the fabrication process. The good shielding performance of the new material is demonstrated by means of shielding effectiveness (SE) measurements on the fabricated samples. Moreover, numerical simulations are performed in order to validate the SE measurements and to design a nanocomposite panel providing a minimum shielding of 30 dB in the frequency range up to 18 GHz.
