本論文利用低壓抽氣沉積法及乾膜轉印法製備奈米銀線 (Silver nanowires) 與奈米碳纖維 (Carbon nanofibers) 之奈米複合導電膜拉伸彈性電極。不同於以往文獻研究的單層導電膜或奈米複合導電膜材料，藉由結合奈米銀線的良好導電性以及奈米碳纖維優異的機械性質，製作出奈米三層 (Tri-layer) 複合導電膜及混摻 (Blending) 複合導電膜，以改進可拉伸彈性電極之性質。
本研究首先製備三種不同的導電膜，分別為純奈米銀線單層導電膜、奈米銀線/奈米碳纖維三層複合導電膜以及奈米銀線/奈米碳纖維混摻複合導電膜，其目的為 (一) 奈米碳纖維的加入能有效提升拉伸彈性電極之穩定性；(二) 加入奈米碳纖維之複合導電膜在拉伸疲勞測試性質上不亞於加入奈米碳管之複合導電膜。對於各導電膜拉伸彈性電極進行一系列電性量測、電子顯微鏡表面觀察及1,000次的拉伸疲勞度測試。
最後結果顯示，加入奈米碳纖維後拉伸電極相較於純奈米銀線擁有較好的電性及拉伸性質，表示奈米碳纖維確實能幫助提升拉伸性質。奈米碳纖維拉伸電極雖在疲勞測試後R/R0值稍比奈米碳管拉伸電極高，但仍維持良好的穩定性；而在電子顯微鏡的觀察下，電極表面產生波浪狀結構，能夠抵銷拉伸過程中所帶來的長度變化。

In this work, stretchable nanocomposite electrodes were successfully fabricated using vacuum evacuation and transferal to PDMS (polydimethylsiloxane). These electrodes consisted of silver nanowires (AgNWs) and carbon nanofibers (CNFs), which can enhance mechanical compliance and electrical conductivity under deformation. They also have excellent properties, including flexibility, stretchability, and bendability. We performed a series of electrical measurements, electron microscope surface observations, and 1,000 stretch and recovery tests on the conductive membranes. The results showed that the conductive stability was improved after adding CNF as CNF/AgNW/CNF and AgNW/CNF nanocomposite electrodes. Because of the differences in the structure between tri-layer and blending electrodes, AgNW/CNF exhibited better performance after 1,000 stretch and recovery tests. In the overall comparison, we also observed that adding CNT in nanocomposite electrodes results in better performance than that obtained by adding CNF because CNT has a higher aspect ratio than CNF. Finally, using SEM, we observed the formation of buckles, which help stabilize resistance during long-term stretch and recovery tests.
