| dc.description.abstract | 電子產品的透明電極目前用的主要材料為透明導電氧化物(transparent conductive oxide，簡稱TCO) ，常用的TCO為ITO (銦錫氧化物)與FTO (氟摻雜的氧化錫)，TCO的導電度雖高但撓曲性不好，不適用於未來的明星科技產業－軟性電子（Flexible Electronics）上。如何製造出一質輕、可撓曲、便宜、穩定且高導電度的電極，是發展軟性電子上一個非常重要的關鍵，本論文的主要研究是如何合成高品質(高導電度、透明度及穩定性)的聚苯胺膜以擴大其用途。我們利用三種簡單的方法來提高聚苯胺膜的導電度，ㄧ為在同步聚合成膜時加入極微量的苯酚添加劑；二則是使用表面型態緻密的載體來沉積苯胺膜；三是利用具有高結晶性的載體來增加聚苯胺膜的規則度。所製得之聚苯胺膜可應用於偵測生物體內左旋維他命C含量、製作導電圖騰、及取代DSSC中Pt作為氧化還原催化劑。導電高分子在實際的應用上除了有導電度低的缺點，另一項大瓶頸即是不易溶解於一般的有機溶劑，雖引進各種取代基可以增加聚苯胺溶解度，但卻造成導電度的大幅度下降。因此本論文使用一種含氟的低沸點溶劑來溶解大量的摻雜態聚苯胺，由此溶液所製備之聚苯胺膜除具有好的規則度與導電度，此簡單的鍍膜製程可以擴展聚苯胺的應用，如取代DSSC中Pt作為催化劑。

| dc.description.abstract | The transparent electrode of the electronics is mainly made with transparent conductive oxide (abbreviated as TCO). ITO (indium tin oxide) and FTO (Fluorine tin oxide) are two of the most commonly used TCO. The conductivity of TCO is high but not flexible, not suitable for applying in the flexible electronics. How to produce an electrode with light weight, flexible, cheap, stable and high conductivity is a very important key point for developing the flexible electronics. This thesis is focus on the synthesis of high quality (high conductivity, transparency and stability) polyaniline (PANI) film to expand its applications. We utilize three simple methods to improve the conductivity of PANI, Fisrt: in situ polymerization of aniline in the presence of a very small amount of phenol additive; Second-: using substrates with dense morphology to deposit PANI film; Third: using high crystalline substrates to increase the ordering of PANI chains deposited on them. The applications of the as-prepared PANI films in sensing ascorbic acid in the organism, to make conducting patterns in a simple and economic way, and to replace Pt as a redox catalyst in dye-sensitized solar cells (DSSCs) were demonstrated. Furthermore, in the real applications of PANI the solubility is also a problem since doped PANI has very poor solubility in common organic solvents. In this thesis, we used a high volatile fluorine-containing solvent to dissolve large amount of doped PANI. PANI film fabicated from this solution has high crystallinity and conductivity. The simple solution process can be expanded the application of PANI such as replace Pt as a redox catalyst in DSSCs.
