MXene, is graphene like two-dimensional material is an attractive candidate for EMI shielding. The MXene coated fabric was fabricated by facile dip coating process and structural features, EMI shielding effectiveness, electric conductivity and wettability were investigated. The coating process generated hydrophobic surface with contact angle of 123°, wetting energy of -39.86 mN/m, 33mN/m work of adhesion and spreading Coefficient of -113mN/m. The composites exhibit excellent thermal stability until 250°C with 5 % weight loss between 250 to 350°C temperature range. The 15-times coated (D15) exhibited higher EMI shielding effectiveness about 43 dB at 2.3 GHz with absolute EMI shielding of 7734.5 dBcm2g–1 and 247.5 dBcm3g-1 shielding effectiveness. The changes of EMI shielding effectiveness of composite was 1 dB/cycle. According to the above result, composite display better outlook application areas like aviation, portable electronics, radars, aerospace and military. |
