The fabricated composite was characterized using Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray (EDX). The prepared composites showed hydrophobic nature with higher contact angle of 126 degrees, -43 mNm(-1) wetting energy, -116 mNm(-1) spreading Coefficient and 30 mNm(-1) lowest work of adhesion. The composites displayed excellent conductivity of 13.68 Scm(-1) with 3.1 sq(-1) lowest sheet resistance. All the composites showed an outstanding thermal stability and constrain highest weight lost until 400 degrees C. The MXene-graphene foam exhibited excellent EMI shielding of 53.8 dB (99.999%) with reflection of 13.10 dB and absorption of 43.38 dB in 8-12.4 GHz. The single coated carbon fabric displayed outstanding absolute shielding effectiveness of 35,369.82 dBcm(2)g(-1). The above results lead perspective applications such as aeronautics, radars, air travels, mobile phones, handy electronics and military applications.
