隨著科技產業的快速發展，許多科技產品推陳出新，也因為時代的淘汰，現階段中常被使用的透明導電薄膜，其中最廣泛使用的氧化銦錫薄膜（ITO），雖有著高透光性以及高導電性之特性，但其價格昂貴，因此近年來轉而尋求其他取代材料，奈米銀線為目前積極研究的導電材料，奈米銀線具有良好的電學特質以及優秀的延展性，隨著各種形式產品的需求，奈米銀線在透明導電薄膜中扮演著重要的角色，本研究將探討合成的銀奈米線並將其應用在透明導電膜上。
本實驗是利用多元醇法將硝酸銀（AgNO3）在1,2-丙二醇（Propylene Glycol, PG）中還原製備銀奈米線。將硝酸銀加入丙二醇配成溶液，在90 °C的環境下使硝酸銀還原成銀奈米顆粒，並加入 1-丁基-3-甲基咪唑氯化物 （1-Butyl-3-methylimidazolium chloride）幫助反應及聚乙烯吡咯烷酮（Polyvinylpyrrolidone, PVP）限制其生長方向，將奈米銀線塗佈於玻璃上製備成透明導電薄膜，並利用紫外光-可見光光譜、原子力顯微鏡、四點探針之分析儀器探討其薄膜均勻度、再現性。此外，也進一步分析薄膜塗佈次數、固含量以及穩定性。

The aim of the thesis is to study the synthesis of silver nanowires by applying it to a transparent conductive film. Based on the data from published papers and results the of experiments the preparation and characterisation of the silver nanowire-based transparent conductive thin film has been analysed and presented. The experiments shows that the sliver nanowires has great electrical properties and extensibility in transparent conductive film. Therefore, the increase demand of various products applying sliver nanowires, has turned such material in to potential components in nowadays technology industry. The thesis then identifies the variables that included in the experiment of the analysation of silver nanowire-based transparent conductive thin film regarding three different aspects: the quantity of solid constant, the coating frequency and the holding time. The detail procedure of the experiment and practical tips for future development has also been provided in the thesis.
By implementing the polyal method, the experiment began on deoxygenating the sliver nitrate （AgNO3） into 1,2 - propanediol (Propylene Glycol, PG). Then, adding the sliver nitrate （AgNO3） in Propylene Glycol for the purpose of deoxygenize the sliver nitrate and transferred it into Sliver Nanoparticle. Followed by adding both the 1-Buty1-3-methylimidazolium chloride to help accelerates the process and the Polyvinylpyrrolidone （PVP） to limit the transferring direction. Finally, analysing the characteristic of Sliver Nanoparticle that applied on the transparent conductive film.
Last but not least, the experiment has successfully produced silver nanowires and applied it onto the transparent conductive film. For going forward, it is suggested that coating silver nanowires onto different material substrates is essential for full-development of its extensibility. Additionally, adding other solvents to increase the firmness are also recommended. The thesis also provides the informations and recommendations for the implementation of the silver nanowires such as producing a extensible mobile phone.
