摘要

本研究之目的是製備透明可撓曲複合薄膜，此透明可撓曲複合薄膜具有良好透光性、低表面阻抗、優良的表面硬度及機械強度等優點。主要之研究方法是將具有高透光性的壓克力單體及樹脂掺入於導電ITO奈米粒子中，再將此複合材料塗佈於擁有可撓曲特性的塑膠基材(PET polyethylene terephthalate )上，給予一能量，使該壓克力單體或樹脂成膜於塑膠基材上，因而獲得透明可撓曲複合薄膜。
研究中，使用不同之製程方法，即紫外光(UV)固化和電漿聚合法，製備抗靜電薄膜。在紫外光固化製程中，可成功獲得穿透度高於85％，表面電阻值為4×103Ω/□，表面硬度3H的透明抗靜電薄膜。在電漿聚合製程中，可利用電漿的操作參數來控制聚合物的性質，增加聚合物的交聯性，因此可成功獲得表面電阻6.6×103Ω/□、透光度高於85%(550nm)、硬度大於4H且接著性高的透明抗靜電複合薄膜。
在薄膜以紫外光固化成膜後，進一步使用電漿或退火處理之方法，成功的將表面電阻值降至6×102Ω/□，將此材料做為有機發光二極體的陽極材料，並成功的點亮元件。

This research dedicated to make transparent ITO thin film with high conductivity using nanoparticles. This thesis was utilized the UV-light curable resin blended with nano conductive ITO particles in different proportions. The mixture was spin-coated on flexible PET (polyethylene terephthalate) substrate and cured by UV irradiation or Plasma to give transparent thin films. The sheet resistance, transparency and sheet hardness of the obtained films are examined. The sheet resistance of the composite thin films (1.5μm) was below 4×103 Ω/□. The UV-visible spectra indicate that the average optical transmittance of ITO films is around 80% in the visible range and surface hardness more than 3H.
The sheet resistance of the polymer films can be achieved as low as 6×102 Ω/□ after the films further treated with plasma or heat annealing. These low resistance films can be used as the electrode layer in varied devices. And it has been successfully applied to be anode in a polymer light-emitting device.
