| Abstract |
A series of multi-walled carbon nanotube (MWCNT) coated carbon fabrics was fabricated with dip coating process, and their performance in thermal conductivity, thermal stability, tensile strength, electromagnetic interference shielding effectiveness (EMISE) was investigated. A solution of MWCNT oxide and sodium dodecyl sulfate (SDS) in water was used in the coating process. MWCNTs were observed to coat the surfaces of carbon fibers and to fill the pores in the carbon fabric. Electrical and thermal conductivities of the composites were 16.42 S/cm and 0.625 W/mK respectively. An EMI shielding effectiveness of 37 dB at 2 GHz was achieved with a single layer of coated carbon fiber fabric, whereas the double layers resulted in 68 dB EMI SE at 2.7 GHz. |
