摘要

本研究係以氯化鐵氧化劑與吡咯在水溶液中，於織物表面(織物選用棉、Nylon 6及PET)以化學聚合方式形成導電薄膜。並以自行合成出金屬奈米微粒溶液(金、銀、銅三種)與吡咯一同聚合形成導電膜並披覆在織物上。織物導電性以四點探針方式測定。織物上的金屬含量由原子吸收光譜儀(AA)量測，並以能量散射光譜儀(EDS)佐證。
實驗結果顯示，反應時添加入奈米金屬溶液，所得到的導電織物表面電阻皆比未添加奈米金屬溶液所產生的導電織物表面電阻來得低。AA數據顯示，金屬存在於導電織物。金大概是最容易併入導電織物的聚吡咯層，銀次之，銅較差。含與不含金屬導電織物表面電阻之差距，與織物金屬含量有些關係，但並非絕對成正比。EDS結果顯示，導電織物除含有C、N、O和金屬元素外，存在陰離子Cl-。導電織物的電磁波遮蔽效益和耐水洗性，有改進的空間。

Pyrrole with various amount of metal nanoparticles including Au、Ag and Cu was chemically oxidized by iron(III) chloride hexahydrate in water and deposited as a polymer film on the surface of fabrics(cotton and nylon 6 and PET).The surface resistivities of above conductive textiles were measured by four-point probe method. The existence of metal on the fabric was identified using atomic absorption spectroscopy and energy dispersive spectrometry.
It indicated that the surface resistivities of metal nanoparticles and polypyrrole coated cotton fabric was lower than that of polypyrrole cotton fabric. The same kind of trend was found for metal nanoparticles and polypyrrole coated nylon 6 or PET fabric. The surface of polypyrrole-coated fibers of metal-containing fabric was smooth according to scanning electron microscopic images. Electromagnetic shielding and resistance of polypyrrole loss for laundry were fair for the conductive fabrics prepared by above method.
