Abstract

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.
