Abstract In order to alleviate the electromagnetic radiation dilemma in the marine environment and reduce the secondary electromagnetic wave pollution, it is necessary to develop an absorption-dominated electromagnetic shielding coating with corrosion resistance. In this work, Ni/Ag-coated Ni (Ni@Ag)/epoxy resin (EP) double-layer coating with high absorption, high electromagnetic interference shielding effectiveness (EMI SE) and good salt spray corrosion resistance was successfully prepared by electroless plating and cold spraying. The coating was constructed with high magnetic Ni/EP as the upper impedance matching absorption layer and high conductivity Ni@Ag/EP as the lower reflective layer. Therefore the electromagnetic wave was easy to enter the interior of the double-layer coating, and could be effectively attenuated by the synergistic effect of magnetic loss and dielectric loss in the absorption layer, the reflection effect of the reflective layer, and the interference effect of the interface. The ultimate product Ni/Ni@Ag/EP double-layer coating exhibited excellent average EMI SE of 64.3 dB and high absorption coefficient of 0.74 in X band. In addition, the salt spray test and electrochemical impedance spectroscopy results proved the satisfactory salt spray corrosion resistance of Ni/Ni@Ag/EP double-layer coating. The output of this study provides a feasible strategy for the design of efficient electromagnetic shielding coating with absorption-dominant characteristics serving in marine environment.

Key words： electromagnetic shielding absorption-dominated double-layer structure salt spray corrosion resistance Ni@Ag
