THz EMI Shielding in Graphene/PMMA Multilayers

The electromagnetic interference (EMI) shielding mechanisms of graphene/PMMA multilayered structures are experimentally investigated by using time domain spectroscopy (TDS) in the THz range. Stacked plates of similar thickness (~5μm), starting from a single layer up to 100 layers, were produced by a...

Description
Summary:The electromagnetic interference (EMI) shielding mechanisms of graphene/PMMA multilayered structures are experimentally investigated by using time domain spectroscopy (TDS) in the THz range. Stacked plates of similar thickness (~5μm), starting from a single layer up to 100 layers, were produced by a novel approach combining ultra-thin polymer casting and wet deposition techniques. These nano laminates show enhanced electrical conductivity (~100 S/cm) and superior specific shielding effectiveness (~2.10 4 dB cm 2 g -1 ).
