Abstract:	中文摘要本研究的主要目的是結合導電性高分子及奈米技術兩項領域，將導電性高分子-聚苯胺在模板中合成管狀結構。實驗中所選用的模板分為無機濾膜-氧化鋁濾膜及高分子濾膜-聚碳酸脂膜，由於兩者的性質截然不同，分別藉由兩種模板合成的聚苯胺管性質上有何差異，目前並無文獻探討。本研究已藉由FT-IR 鑑定模板中合成的產物確實是聚苯胺結構。並且以SEM、TEM 分別觀察兩者模板合成的聚苯胺管表面型態之間的差異，證明了氧化鋁濾膜內電化學合成之聚苯胺管表面型態較好。再藉由ESR 探討兩者聚苯胺管電子非定域化程度，得到氧化鋁濾膜內電化學合成的聚苯胺管有較好的電子非定域化程度。從導電度的測試結果得知，200 nm 氧化鋁濾膜內電化學合成之聚苯胺管相較於聚苯胺塊材也有較好的導電度值。本研究在相同模板下分別以電化學法及化學法合成聚苯胺管，並且藉由SEM、TEM、ESR 及導電度討論電化學法及化學法對合成聚苯胺管有何影響。得到電化學法合成之聚苯胺管有較佳的性質。由於聚碳酸脂膜的孔徑變化較多且容易購得，本研究將以多樣規格之聚碳酸脂膜當做模板合成各種孔徑大小之聚苯胺管，並探討其性質發現，在孔徑愈小的聚碳酸脂膜內合成聚苯胺管會有單體溶液及氧化劑擴散的問題存在。最後，本研究自行製作孔徑60 nm、膜厚30 μm 且孔道均一的氧化鋁濾膜，並藉由它當做模板電化學合成60 nm 聚苯胺奈米管。 Abstract The purpose of this study is to combine conducting polymer with nanotechnology, by synthesis of polyaniline tubes inside the pore of templates. In this study, both the inorganic membrane: Anodsic alumina membrane and polymeric membrane: polycarbonate track-etched membrane are used as templates to synthesize polyaniline tubes. Owing to different characters of the two templates, it may effect the polyaniline tubes synthesized in them. However the properties of those tubes synthesized in different templates have not been carefully studied so far. FT-IR spectra show that the products synthesized inside the pores of templates are polyaniline. The morphologies of polyaniline tubes have been compared using SEM and TEM. The morphologies of polyaniline tubes synthesized electrochemically in the Anodsic membrane are better than the others. ESR spectra reveal that the degree of delocalization of those tubes synthesized electrochemically in the Anodsic membrane are better. The tubes synthesized inside the pore of Anodsic membrane electrochemically show an enhancement of the electronic conductivity compared to polyaniline bulk materials. The polyaniline tubes by electrochemical synthesis will be shown to have better properties compared to those tubes of chemical synthesis in the same kind of templates using SEM、TEM、ESR and conductivity measurement. With decreasing the pore diameter of polyaniline tubes, the degree of delocalization increases. Self-organized 60 nm Anodsic alumina membrane has been synthesized successfully by two-step anodizing process, and polyaniline tubes(rods) of 60 nm has been synthesized electrochemically inside the pores.
