The miniaturized electric/electronic devices grown rapidly in modern society create undesirable electromagnetic interference (EMI) that can have detrimental effects on the performance of electronic systems and human health. So, the inhibition of undesirable EM radiations has become an important field in materials science. Metals have been widely used against EM pollution. However, their high density and difficulty in processing have limited their applications for EMI shielding. In this study, to attain advanced materials with high performance in EMI shielding and flexibility, MXene and Ni layers were introduced on PET nonwoven by a combination of dip-coating and electroless plating coating processes. The microstructural features of MXene/Ni-coated PET fabrics were characterized using SEM, EDS, XPS, and XRD. The electrical conductivity and EMI shielding performance were also investigated using electrometry and network analysis in a wide frequency range of 1-18 GHz, respectively.
