Abstract
Polyamide 6 (PA 6)/multiwalled carbon nanotube (MWCNT)-coated cotton fabrics having varying amounts of MWCNTs (10, 12, 14 and 16 wt.%) in PA 6 (10, 15 and 20 wt.%) were fabricated with dip coating method to investigate the electromagnetic shielding properties in the frequency range of 15–3000 MHz. The effects of MWCNT loading on electrical resistivity, electromagnetic interference shielding effectiveness and also shielding mechanism have been studied. The highest electromagnetic shielding effectiveness value was obtained at 20 wt.% MWCNT loading in 10 wt.% PA 6 and the PA 6/MWCNT-coated composites showed the absoprtion-dominated shielding mechanism.
