EMI shielding flexible thin films based on graphene-MWCNT nanocomposites

This work presents a facile method for preparation of thin flexible films starting from inks based graphene oxide and MWCNT embeded in a polymer PEDOT:PSS matrix. The EMI shielding efficiency was evaluated for films thickness in the range of 10-20 microns, results revealing values up to -40 dB in X band frequency for graphene-MWCNT nanocomposites.
