摘要

透明導電薄膜在當今光電元件中扮演著重要的角色，它除了需要擁有優異的導電性質之外，還必須兼具可見光頻譜的薄膜穿透性。隨著材料與技術的發展，今日金屬網格(metal mesh)技術已經能夠利用奈米材料，讓原本擁有良好的導電性但可見光的透光性差的金屬薄膜，能夠透過網格結構的製作技術，設計出兼具導電性及穿透性的透明導電薄膜。
本論文利用直徑40.5nm長度15.2µm的針狀奈米銀線(silver nanowires)研究以旋轉塗佈法(spin coating)製作出均勻分布的透明導電薄膜，再使用隔水加熱法使其固化成穩定的金屬網格薄膜結構。經研究發現，我們所製作的奈米銀線薄膜在可見光的穿透率可達75 %以上，薄膜之片電阻值可低於25 Ω/□，導電率可達6.62×10^2 Ω-1cm-1，並成功地將其製作成OLED元件之電極。

Transparent conductive film is an important character for Electro-Optical elements nowadays. It needs good conductivity and also needs higher transmittance in the visible range. Metal mesh is a new technology. It uses nanomaterials to produce transparent conductive thin films. Metal materials have best conductivity but it is difficult to shine a light through. Now, it can devise thin films both have conductivity and transmittance by metal mesh technology,
In this thesis, we use silver nanowires (the diameter is 40.5nm and the length is 15.2µm) to make uniform transparent conductive thin films by spin coating, then we let it cured to become a stable metal mesh structure by double boiler method. According to experiments, we have produced the silver nanowire thin film which its transmittance is over 75% in the visible range, its sheet resistance is less than 25Ω/□ and its conductivity can reach 6.62×10^2 Ω-1cm-1. Finally, we can take the thin film as electrode of Organic light-emitting diode.
