本研究我們嘗試利用靜電紡絲技術研製高性能銀奈米纖維網格的透明電極。透明電極在顯示器和太陽能電池元件組裝上是不可或缺的基板，目前以銦錫氧化物(ITO)薄膜為主導，然而高價格的銦、膜的脆性和高真空蒸鍍法限制了他們的應用。近來，網格奈米結構如碳奈米管(CNTs)、石墨、和銀奈米線在作為替代品上吸引了極大的關注。因此本計畫擬將PVA-AgNO3水溶液利用靜電紡絲技術製作出PVA-AgNO3奈米纖維網格，並經煅燒、金屬Ag還原等製程，研製出高性能銀奈米纖維網格的透明電極。實驗中將使用靜電紡絲成膜收集設備，並調整靜電紡絲不同工作電壓、紡絲溶液濃度、溶液流速、工作距離與針頭號數等參數，並利用掃描式電子顯微鏡(scanning electron microscope, SEM)觀察不同電紡纖維膜之結構、纖維細度與直徑平均分布(mean distribution of diameter)，以及測量奈米纖維膜孔洞大小、比表面積與表面導電性。

In this study, we attempted to develop a silver nanofiber web as a high-performance transparent electrode by using electrospinning techniques. Transparent electrodes, as an indispensable substrate for displays and solar cell elements, are currently dominated by indium tin oxide (ITO) films; however, the high price of indium, film brittleness, and high vacuum deposition have limited its application. Recently, web nanostructures such as carbon nanotubes (CNTs), graphite, and silver nanowires have attracted much attention as replacements. Therefore, this project intentionally used a PVA-AgNO3 aqueous solution with an electrospinning technique to produce a PVA-AgNO3 nanofiber web. Through calcination, Ag reduction processes were utilized to develop high-performance transparent electrodes consisting of a silver nanofiber web. Throughout the experiments, an electrospinning film collecting device was utilized, and the electrospinning parameters were adjusted, with the operating voltage, spinning solution concentration, solution flow rate, operating distance, and needle size numbers being varied. A scanning electron microscope (SEM) was then used to observe the different elestrospun fiber film structures, fiber fineness, and mean distribution of the diameter. In addition, the transmittance, absorbance and surface conductivity of the nanofibers webs were measured.
