Graphene-Based Electromagnetic Absorbing Textiles for 5G Frequency Bands

The feasibility of graphene based absorbing textiles for electromagnetic absorption at 5G frequency bands is investigated. With this aim, a novel manufacturing method for the production of polyvinylidene fluoride (PVDF) coatings filled with graphene nanoplatelets is investigated. The produced samples are morphologically characterized and the electrical and electromagnetic properties are assessed. In particular, the effective complex dielectric permittivity is measured in the Ku-band and the results are used to predict by simulations electromagnetic properties of the graphene based coatings for frequencies up to 40 GHz. Finally, the radar absorption properties are measured for frequencies up to 40 GHz.
