MWCNT coated carbon fabrics composite were fabricated by using facile dip coating process. The thickness and fissures of the fabrics were altered by using oxidized MWCNT/SDS dispersed solution. The coating process significantly affect the tensile strength, electrical conductivity, EMI shielding of the composites. The composite exhibit excellent thermal restrains up to 284°C with 0.63 W-1K-1 maximum thermal conductivity. The composite displayed 16.42 S cm−1 higher electrical conductivity with 3.3 Ω/sq low sheet resistance. 68 dB of highest EMI shielding shown double layer fabric at 2.7 GHZ whereas singly coated fabric exhibited 37 dB maximum EMI shielding at 2 GHz with 486.54 dBcm3g-1 specific SE and 35000 dBcm2g-1 absolute SE. According to the above-mentioned results leads the composite for the potential shielding applications such as aeronautic, military, automobile and portable electronic devices. |
