摘要

本研究是將多壁奈米碳管(MWNTs)經氧化、酸化改質後，使其表面與末端接上羧基(-COOH)，再將其加入BPDA(3,3’,4,4’- Biphenyl tetracarboxylic dianhydride)與p-PDA (p-phenylenediamine)合成聚醯亞胺前驅物聚醯胺酸（PAA）中，形成PAA/MWNTs複合材料，再配合旋轉塗佈及階段性熱熟化步驟得到聚醯亞胺-多壁奈米碳管複合材料。在此研究中加入多壁奈米碳管於基材的目的是為了提升基材的機械性質和電性性質。探討未改質多壁奈米碳管與改質多壁奈米碳管添加入聚醯胺酸（PAA）中對聚醯亞胺-多壁奈米碳管複合材料的影響。本研究中使用能量分散光譜儀(EDS)來鑑定多壁奈米碳管純化效果，熱重損失分析儀（TGA）、鉛筆硬度計(Hardness Pencil Test)、萬能試驗機(Universal Test Machine)分別測定材料的熱穩定性質和機械性質，傅立葉轉換紅外光譜儀（FTIR）來鑑定其化學結構，掃描式電子顯微鏡（SEM）與穿透式電子顯微鏡(TEM)來觀察材料的剖面型態與奈米碳管和基材之間的分散性，超絕緣量測儀量測材料的電性。

In this research, MWNTs were oxidized and then modified with carboxylic groups(-COOH) on the surface and the end. After that, the modified MWNTs were added to poly(amic acid) (PAA, precursor of polyimide) which were reacted from BPDA and p-PDA to synthesize PAA/MWNTs composite material. The PI/MWNTs composite were obtained by spin coating and multi-wall thermal curing step process. In this study, the MWNTs were introduced into the matrix in order to increase its mechanical and electrical properties. The effect to PI/MWNTs composite of unmodified and modified MWNTs were also discussed. In this research, purified MWNTs are characterized by energy dispersive spectroscopy (EDS). The thermal properties and mechanical properties were analyzed by Thermogravimetric analysis (TGA) and Hardness Pencil Test and Universal Test Machine, respectively. The structure of prepared PI-MWNTs was characterized by Fourier transform infrared (FTIR) spectrometry. The morphology of PI-MWNTs were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The electrical conductivity was analyzed by Super Megohmmeter.
