有機材料具備可撓曲特性且成本低廉,能夠以壓印技術快速製作有機高分子圖案,發展有機元件成本低廉,具量產潛力。本論文使用導電高分子[聚(3,4-二氧乙基塞吩) / 聚苯乙烯磺酸]為懸浮水溶液,在製作微米級圖案上有其困難之處,因此使用逆壓印製程─微轉印成形,控制濃度、溫度及壓力,再配合疏水基板,可製作出深寬比約為1:1且無殘留層的圖案。
本論文開發新穎的逆壓印製程─溶劑輔助式逆壓印,控制溶劑(水)含量,可快速轉印導電高分子電極,所製作圖案之解析度可達2.5μm。由於導電高分子[聚(3,4-二氧乙基塞吩) / 聚苯乙烯磺酸]導電率僅約為0.25 S/cm,因此添加有機溶劑(DMSO)使其導電率提升至236±10 S/cm,如再添加金奈米棒,將可提升至376±15 S/cm。
本論文亦轉印導電高分子電極製作電子元件,包括(1)滴定法沉積氧化鋅奈米棒於PEDOT : PSS電極間,製作二極體。(2)以導電高分子製作成電晶體源極與汲極,配合低阻值矽閘極與有機小分子─五環素半導體層,製作薄膜電晶體,電流開關比(Ion / Ioff)約為100,以及載子遷移率約為0.007cm2/V-s。另外混合導電高分子[聚(3,4-二氧乙基塞吩) / 聚苯乙烯磺酸]與氧化鋅奈米棒(重量比值為0.89)製作複合膜,可作為紫外光感測器。
Organic devices with advantages of flexibility could make with pattern of organic polymer quickly by imprinting. It has low cost and potential of output for developing organic devices. The conducting polymer (PEDOT : PSS) is water soluble slightly, so it is difficult to make micropatterns by photolithography process. We use reversal imprinting – microtransfer molding to prepare conducting polymeric patterns without residual layer with aspect ratio about 1:1 under appropriate conditions of polymeric concentration, imprinting temperature, and pressure to avoid scaling pattern.
This thesis also shows a kind of novel reversal imprinting – solvent assisted reversal imprinting. We only control the content of solvent (water) precisely to be able to transfer conducting polymeric patterns onto substrate quickly and effectively. The resolution of conducting polymeric patterns can achieve the size of 2.5μm. The conductivity of bare PEDOT : PSS is enhanced from 0.25 to 236±10 S/cm through organic solvent addition. The conductivity of solvent – PEDOT : PSS is further enhanced from 236±10 to 376±15 S/cm as added with Au nanorods.
The transferred conducting polymeric patterns have been demonstrated for applications : (1) drop deposition of ZnO nanorods between the transferred conducting polymeric patterns to fabricate Schottky diode, (2) combine pentacene-based TFT with SiO2 as gate dielectric layer to have Ion/Ioff of 100 and mobility of 0.007cm2/V-s. Besides, we use PEDOT : PSS / ZnO nanorods composite film to fabricate UV light sensor.
