A powerful approach to graphene/stainless steel web hybrids for large scale electromagnetic shielding applications

Graphene/Stainless Steel web hybrids were fabricated using soaking-annealing method. The microstructure was characterized by field emission scanning electron microscope an X-ray diffraction. The results showed that Graphene uniformly dispersed on the surface of stainless steel fibers which were further prepared to large scale graphene/Stainless steel web. For the as-prepared products a minimum reflection loss (RL) of −42.6 dB was achieved at 8.5 GHz. Moreover, the frequency range with RL peak value below −10 dB was achieved in a broad frequency bandwidth of 9.8 GHz, suggesting the excellent microwave absorption properties. - Highlights: • Large-scale graphene/stainless steel web hybrids were successfully fabricated. • The architectures exhibit excellent microwave absorption property. • The described method has high probability to develop in industrial application.
