Abstract
High-performance electromagnetic interference (EMI) shields are urgently required due to more and more serious electromagnetic pollution. In this work, nickel/reduced graphene oxide-coated glass fabrics modified with poly(dopamine) (Ni/RGO-PDA) were prepared by dipping and electroless deposition for EMI shielding. The synergistic effect of poly(dopamine) and RGO is beneficial to nickel electroless plating and the establishment of conductive network. Ni/RGO-PDA-coated glass fabrics show low resistance of 0.231 Ω sq−1. The heating temperature of Ni/RGO-PDA-coated glass fabrics is steady at around 168 ℃ when they are exposed to a low voltage of 2 V. In addition, EMI shielding effectiveness (SE) of Ni/RGO-PDA-coated glass fabrics ranges from 62 to 88 dB in the range of 2–18 GHz, which could even be maintained after corrosion. The result indicates that Ni/RGO-PDA-coated glass fabrics exhibit excellent electrical conductivity, heating property, and EMI SE, which could be promisingly used as flexible conductive fabrics, electric heating, and electromagnetic shielding materials.
