Flexible films based on graphene/polymer nanocomposite with improved electromagnetic interference shielding
In this paper a method to obtain a graphene/polymer nanocomposite film laminated into a PET sandwich structure with improved EMI shielding was investigated. The composite was characterized by FTIR spectroscopy, X-ray diffraction, AFM, SEM microscopy and Raman spectroscopy. The EMI shielding effectiveness was evaluated in 8-12.5 GHz X-band frequencies for different ratio between graphene filler and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate matrix at different thickness of nanocomposite.
