Since organic light-emitting diodes (OLEDs) are extremely sensitive to water and oxygen, their encapsulation is essential. Regarding encapsulation technology using nanoparticle-polymer resin composites, along with the hygroscopicity of the nanoparticles, the dispersibility of the nanoparticles and their miscibility with the resin are also important factors. Herein, the optical and encapsulation properties of nanoparticle-polymer resin composites prepared by dispersing surface-modified MgO nanoparticles (MNPs) with surface modifiers having different hydrocarbon chain lengths in acrylate resin are compared. The nanocomposite-containing surface-modified MNPs with long hydrocarbon chains exhibited the best optical and encapsulation properties (transmittance: 94.9 %, haze: 2.3 %, and device performance half-time: 528 h) due to high dispersibility and miscibility with the polymer resin.

由于有机发光二极管（OLED）对水和氧气极为敏感，因此必须对其进行封装。关于使用纳米颗粒-聚合物树脂复合物的包封技术，连同纳米颗粒的吸湿性，纳米颗粒的分散性及其与树脂的混溶性也是重要因素。本文中，比较了通过将具有不同烃链长度的表面改性剂的表面改性MgO纳米颗粒（MNPs）分散在丙烯酸酯树脂中而制备的纳米颗粒-聚合物树脂复合材料的光学和封装性能。具有长烃链的含纳米复合材料的表面改性MNP表现出最佳的光学和封装性能（透射率：94.9％，雾度：2.3％，并且器件性能为半衰期：
