Transparent nanocomposites, which are optically transparent and mechanically robust, have been drawn numerous interests for various applications, including adhesives, encapsulants, and other functional coatings. We demonstrated high-performance transparent nanocomposites with robust organic polystyrene nanoparticles (NPs) for optoelectronic devices. By optimizing the crosslinker concentration, the NPs improved their thermal stability and solvent resistance, allowing the NPs to be utilized in broad fields. Based on the nanoindentation results, we confirmed that the mechanical properties and elastic modulus were improved. We verified that the light-emitting diode encapsulation with this nanocomposite can enhance light-extraction efficiency by up to 10%, thereby suggesting the high optical clarity of nanocomposites with organic NPs.
