MXene-graphene-polymer composite were prepared by spray coating and solvent casting method. The fabricated composites displayed hydrophobicity with uppermost 126° contact angle, -116 mN/m spreading Coefficient, 30 mN/m lowest work of adhesion and -43 mN/m wetting energy. The composites exhibited excellent conductivity of 13.68 S/cm with sheet resistance of 3.1 Ω/sq. All the composite prevented weight lost up to 400°C with outstanding thermal stability. The MXene-graphene foam showed 41 dB of excellent EMI shielding at 2.97 GHz frequency with 36 dB average EMI shielding and 1324.29 dBcm2g–1 absolute shielding effectiveness. Mono layer graphene coated fabric showed exceptional absolute shielding effectiveness of 35370 dBcm2g–1 with shielding effectiveness of 453 dBcm2g-1 and 33 dB of maximum EMI shielding at 2.17 GHz. Hence, above results standpoint the applications such as handy electronics, mobile phones, aeronautics, air travels, radars, and military applications. |
