Abstract
MXene and nonwoven carbon fabric are good candidate for flexible, light-weight electromagnetic interference (EMI) shielding fabric. The prepared composite was characterized using X-ray diffraction, X-ray photo electron spectroscopy, energy-dispersive X-ray spectroscopy, scanning electron microscope, mapping, and Raman spectroscopy. The 15 times coated composite displayed a contact angle of 123, a wetting energy of − 39.86 mN/m, a spreading coefficient of − 112.66 mN/m, and 32.94 mN/m work of adhesion. The fabricated composites inhibited thermal degradation until 235 C. The composite revealed an excellent electric conductivity of 8.5 S/cm with a sheet resistance of 6.5 Ω/sq. The composite showed a maximum EMI shielding of 43.2 dB at 2.3 GHz with 8534.7 dB cm2/g. The composite displays better outlook application areas such as aviation, portable electronics, radars, aerospace, and military.
