Abstract

In this paper, electrodeposition was successfully used to prepare a kind of polyester fiber flexible broadband shielding material based on PET fabric. The Ni-Fe alloy coating prepared by electrodeposition can completely and evenly cover the substrate. The maximum saturation magnetic moment was 93.16 emu/g. The sample with the highest permeability was prepared through the process exploration experiment. The permeability increases first and then decreases with the increase of Fe content in the coating. The phase with the highest permeability in the coating is Ni₃Fe. The simulation results show that the shielding effect of Ni-Fe/Cu layer was better than that of Cu/Ni-Fe layers. The optimal shielding effectiveness can reach 28.4db in 10 kHz magnetic field and 80 dB in 100k∼10 MHz magnetic field. In the electromagnetic field of 30M∼18 GHz, the shielding effectiveness is greater than 85 dB, up to 110 dB. The tensile strength of the shielding fabric is 91.63 MPa, the displacement is small, and the material has no obvious elasticity. During the stretching process, the coating breaks first, and then the PET fabric breaks.
