本研究以自行合成之金屬奈米粒子(Au、Ag、Cu)預先吸附在織物(PET、尼龍6、棉)，再擴散吸附吡咯，最後以FeCl3氧化，製備導電織物。含聚吡咯尼龍6、PET和棉導電織物其表面電阻最低可分別達87±6、214±13和228±11Ω/square。含金屬聚吡咯導電織物中，尼龍6織物表面電阻48±10 (金)、52±10 (銀)、38±1(銅)。 PET織物表面電阻122±8(金)、154±10(銀)、118±3(銅)，棉織物表面電阻150±10(金)、157±14(銀)、114±12(銅)。上述導電織物表面電阻皆低於不含金屬導電織物之表面電阻。
織物金屬含量以原子吸收光譜儀檢測，並以能量分散光譜法佐證，數據顯示，導電織物含有金屬，金在纖維中含量最多。SEM影像顯示，聚吡咯層均勻分散於纖維上，形成導電通路，但是纖維間隙未填滿。預吸附的金屬粒在織物上分散良好，銅所形成的粒子較大。電磁波遮蔽效果以尼龍6最佳(8-28dB)，PET次之(7-15dB)，棉較差(5-9dB)，也說明低的織物表面電阻是好的電磁波遮蔽因素之一。以水洗測試導電織物，發現表面電阻上升3個級數以上，說明織物牢度尚需要加強。

Fabrics including cotton, nylon 6 and poly(ethylene terephthalate) were pre-adsorbed metal nanoparticles(Au、Ag and Cu) and diffused with pyrrole. These fabrics were chemically oxidized by FeCl3 in water. Polypyrrole has been found incorporating into interior of fibers and spacing between fibers. The resistivities of polypyrrole and nanoparticles contained fabrics were lower than those of fabrics containing polypyrrole(30 to 100 Ω/square). The existence of metal nanoparticles in fabric was identified by atomic absorption spectroscopy and electron dispersive spectroscopy. Gold loading of the conductive fabric was high comparing to two other metals.
Dispersion of preadsorbed metal nanoparticles on the surface of fibers of pristine fabric was good according to images taken from electron scanning microscope. Electromagnetic shielding of the conductive fabrics were significant 8-26dB(nylon 6)、7-15dB(PET) and 5-9dB(cotton)，although resistance of polypyrrole lose during laundry was fair for above textiles.
