近年來，人們常利用奈米銅線製成透明導電電極以取代傳統氧化銦錫電極，銅的優點為天然豐度比銀高了1000倍，因此價格便宜，而導電度也只比銀稍低，且所製成奈米銅線配成導電油墨並噴塗於PET薄膜上，將會擁有可撓曲性，此特性相較於傳統氧化銦錫電極更可應用於穿戴裝置、平面顯器、感光元件等。
合成奈米銅線需要銅離子來源、還原劑、封端劑。本研究中，我們將以氯化銅作為銅離子來源，還原劑將使用葡萄糖或抗壞血酸，封端劑將使用十六或十八烷基胺，在不同還原劑、封端劑的情況下比較所得到的奈米銅線的型態、直徑、長度、長徑比，並利用旋轉塗佈，塗佈上聚甲基丙烯酸甲酯(PMMA)增加銅線的抗氧化性，並測定透光度、電阻率。

Recent years, people often use copper nanowires to produce transparent conductive electrodes to replace traditional indium tin oxide electrodes. The advantage of copper is its natural abundance is 1000 times higher, lower price, and slightly lower conductivity than silver. The copper nanowires is made into conductive ink can be sprayed on PET film of hugh flexibility. Compared with traditional indium tin oxide electrodes, this feature can be applied to wearable devices, flat-panel displays, photosensitive elements, etc.
To synthesis of copper nanowires requires copper ions, reducing agent, and capping agent. In this study, we will use copper chloride as the source of copper ions, glucose or ascorbic acid as the reducing agent, and hexadecylamine or Octadecylamine as capping agent. The shape, diameter, length and aspect ratio of the obtained copper nanowires will be compared. Polymethyl methacrylate (PMMA) will be further coated to increase the oxidation resistance of the copper nanowires. The transmittance and resistivity will be also examined.
