We demonstrate that a 20 nm-thick graphene/Ni hybrid mesh can provide EMI shielding effectiveness (SE) exceeding 12.1 dB (?93.6% power attenuation) in the decimeter band while retaining a high visible transmittance of ?83%. Its maximum achieved SE value was 26.6 dB (?99.5% power attenuation) at 0.75 GHz. Furthermore, the thicker Ni mesh exhibited a higher EMI SE. Compared to a conventional Ni mesh, the hybrid mesh exhibits a higher SE and a greatly improved corrosion resistance. The graphene coating is directly grown on a Ni mesh via rapid annealing of solid carbon precursors under low vacuum. Scalable fabrication of the mesh was achieved by a self-formed TiO2 crack network template. Our results not only provide a promising material for high-performance EMI shielding in optoelectronics devices but also enable applications of EMI shielding in harsh environments. ? 2020 American Chemical Society.Corrosion resistance; Electromagnetic pulse; Electromagnetic wave interference; Graphene; Hybrid materials; Mesh generation; Nickel coatings; Oxide minerals; Shielding; Signal interference; Titanium dioxide; Electromagnetic interference shielding; EMI shielding effectiveness; Graphene coatings; Harsh environment; Optoelectronics devices; Power attenuation; Transparent graphene; Visible transmittance; Electromagnetic shieldingjournal article10.1021/acsanm.0c010762-s2.0-85092222272
