本研究在製作奈米銀線複合式電極，以奈米銀線與PEDOT:PSS (PH1000)所組成的「複合式導電薄膜」應用於有機光電元件，以取代透明氧化銦錫(Indium Tin Oxide, ITO)電極，未來更可以此發展製作可撓式有機光電元件。研究中使用透明矽膠「聚二甲基矽氧烷(Polydimethylsiloxane, PDMS)」疏水性及親水性的特性及極性溶劑「二甲基亞碸(Dimethyl Sulfoxide, DMSO)」對奈米銀線複合式電極溶液薄膜進行處理，最後製做有機發光二極體。
使用固定濃度之奈米銀線(Silver Nanowires, AgNWs)水溶液參雜PEDOT:PSS (PH1000)來配製不同濃度之奈米銀線複合式電極溶液，探討單層與堆疊多層形成薄膜後之差異以及薄膜面電阻、薄膜穿透度、薄膜表面型態與粗糙及使用PDMS固化成薄膜，且探討氧電漿處理時間與PDMS表面親水性之關係。在本研究發現當氧電漿處理時間為60分鐘時，PDMS薄膜在金屬遮罩定義的電極範圍能完全呈現親水性的狀態且當體積比奈米銀線酒精混合溶液：PEDOT:PSS (PH1000)為1：19時，奈米銀線複合式電極有最好的表現，面電阻為108 Ω/sq，可見光波段平均穿透度為83%，表面粗糙度RMS小於10 nm。
當我們利用此PDMS轉印方法備製的AgNWs製做成有機發光二極體(Organic Light Emitting Diodes，簡稱OLED)元件後，可以發現此元件發光穩定，不會有閃爍的情形發生，解決了實驗室以往AgNWs電極嚴重漏電的問題。

In this study, we produce the compound silver nanowires electrodes with silver nanowires and PEDOT:PSS (PH1000). The electrodes would apply in organic light emitting diode (OLED), and look forward to replace indium tin oxide (ITO). In the future, the hybrid film could be used to manufacture the flexible organic electro-optic devices.
To enhance the conductivity of the compound electrodes, we use dimethyl sulfoxide (DMSO) to treat the solvent of compound silver nanowires electrodes by soaking method. Also, to reduce the roughness of the compound electrodes, we utilize PDMS to solve the roughness of compound silver nanowires electrodes via transferred method. At last, we could use the thin film electrodes to produce OLED.
In this research, we investigated the sheet resistance of compound electrodes, optical transmittance, surface roughness and surface morphology. Then, we found that there is the best hydrophilicity at PDMS film by ozone treatment sixty minutes. In this experiment, the appropriates volume ratio of silver nanowires aqueous solution, and PEDOT:PSS (PH1000) is 1：19 . The thin film produced by this solvent get great performance, sheet resistance 108 (Ω/sq), keeping the average transmittance achieve 83 % in the wavelength of visible light, and the surface RMS is lower than 10 nm.
Via measurement results of organic electro-optic devices, we found that even though the surface RMS of compound silver nanowires electrodes is about 1.8 nm, the problem of leakage is still existence. Consequently, the process of compound silver nanowires electrodes is not only care about the conductivity and optical transmittance, but also have to solve the problem of leakage on account of the silver nanowires overlap.
