摘要: 本論文在探討利用環氧樹脂,進行陽離子型UV光固化聚合反應,應用於有機元件上之封裝。研究結果發現,樹脂配方經固化後,其具有高的玻璃轉移溫度(Tg ≧110℃),對於玻璃基材也有優異的附著性(≧2.0 kgf/mm2),具有極低的收縮性(≦4%),及高阻水氣穿透效果(WVTR≦10 g/m2-day)。將此樹脂配方應用在有機元件的封裝上,結果發現到可以延長有機發光二極體(OLED) 以及有機太陽能電池(OPV)元件的壽命。尤其是OPV元件在經封裝後,放在大氣環境下可以維持超過1,000小時其元件效率仍為原值的60%。
In this study, UV-curable epoxy resins were used to encapsulate the organic devices. The epoxy resin shows a high glass transition tem-perature (Tg ≧110℃), good adhesion to the glass substrate (≧2.0 kgf/mm2) after UV curing. The encapsulant reveals a very low volume shrinkage (≦4%), high water vapor transmission resistance ability (WVTR ≦10 g/m2-day). In this study, the epoxy resins were used to encapsulate the organic device such as organic light-emitting diode(OLED) and organic photovoltaics(OPV) devices. The results demonstrate that the lifetime of the encapsulated devices is enhanced. For the OPV devices, their PCE values are around 60% of original values af-ter keeping the encapsulated device in atmosphere for 1,000 hrs.
