THz and microwave properties of 3D-printed nanocarbon based multilayers

We propose a new type of light-weight conductive thin film material having good mechanical properties and electromagnetic shielding efficiency. For that 3D printing through layer-to-layer deposition of nanocarbon containing plastic layers and neat polymer layers was combined with hot pressing to obtain 10 μm thick films. We show that such composite has Re e ≍ Im e in very broad frequency range, 200GHz–0.6 THz.
