Abstract |
The sequence of thin MXene-CNTO-SDS coated wet laid non-woven carbon fabric was manufactured with low density and low porosity. The fabricated composite was characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS). The fabricated composite showed excellent electric conductivity of 12.8 S/cm with lower sheet resistance 2.75 Ω/sq. The composite exhibited excellent thermal stability and constrained the degradation until 200°C with 8% of weight loss between 200 to 500° temperature range. Twenty-five times coated carbon fabric (MXCNTC25) displayed highest EMI shielding approximately 40 dB at 2.3 GHz with specific EMI shielding (SSE) of 214 dBcm3g-1 and absolute EMI shielding (SSE/t) 7523.78 dBcm2g-1. According to aforementioned above result, the fabricated composite displays excellent properties towards the application areas like mobile phones, aeronautics, radars and military applications. |
