本研究將多層奈米碳管(multi-walled carbon nanotube, MWNT)表面以過氧化琥珀酸(succinic acid acyl peroxides, SAAP)改質成MWNT-C2H4COOH，再進一步將MWNT-C2H4COOH與螯合性高分子PPG-g-FA接枝反應成MWNT-PPG-g-FA，及直接胺化成MWNT-C2H4NH2；將三種改質碳管分別分散在水及有機溶劑中並分析其分散性及粒徑大小。將聚(4-乙烯基吡啶)(poly(-4-vinylpyridine), P4VP)披覆於PET表面製成具吸附能力之改質PET(以下稱P4VP/PET)，以浸塗法(dip-coating)將改質MWNT藉由疊層組裝(layer-by-layer assembly)方式吸附於P4VP/PET表面，形成一可撓式多層奈米碳管薄膜，並在該碳管薄膜上進行銀離子之螯合-還原反應，以製備成一含銀奈米顆粒之多層奈米碳管薄膜。以掃描式電子顯微鏡(SEM) 、X射線光電子能譜儀(XPS)、四點探針(four point probe)及紫外光譜儀(UV-vis)了解多層奈米碳管薄膜之表面形態(morphology) 、表面元素鍵結、電性質及透光性，以達到製備疊層組裝之含銀奈米粒子多層奈米碳管可撓式導電薄膜之效果。

Modified multi-walled carbon nanotube (MWNT), MWNT-C2H4COOH, obtained by the reaction of MWNT with succinic acid acyl peroxide (SAAP), reacted sequentially with SOCl2 and PPG-g-FA to afford another modified MWNT, MWNT-C2H4CO-PPG-g-FA (denoted as MWNT-PPG-g-FA). MWNT-C2H4COOH reacted with azide (N3-) ion to yield the third modified MWNT, MWNT-C2H4NH2. The dispersedness and particle size of the three modified MWNTs in water were investigated. The modified poly(ethylene terephathalate, PET) film which could form hydrogen bond with the modified MWNTs was prepared by spin-coating of P4VP on the PET film (called P4VP/PET). The transparent MWNT conductive film decorated with Ag nanoparticles was prepared by dip-coating the modified MWNTs via layer-by-layer assembly on the P4VP/PET and followed by chelating-reducing the Ag+ ions on the MWNT conductive film. The conductivity and the optical transmittance of the film were recorded by 4-point probe and UV-vis spectrometer. The morphology of and the existence of silver on the film were investigated by the scanning electron microscope (SEM) and the X-Ray Photoelectron Spectroscpoe (XPS).
