Show more >With the growing penetration of microwave applications in modern society, exposure to electromagnetic waves (EMWs) may become an important public health problem. In addition, the coexistence of high frequency devices and systems induce electromagnetic Interferences (EMIs) leading to electromagnetic pertubations and lifetime reduction. consequently, shielding materials capable of blocking EMWs are highly needed. In this paper, composite materials based on graphene oxides and silver nanowires were studied as potential EMW shielding materials. Composites were obtained from graphene oxide (GO) with sheet size between 150 and 2000 nm and thicknesses of flakes in range 2–5 nm. Average thickness of free-standing films were around 14.8 μm . We studied the ratio between these nanomaterials to modulate shielding efficiency in a broad microwave frequency range up to 18 GHz. The shielding efficiency of around 6.5 dB was measured for the r-GO free-standing film.Show less >
