Nanocomposite, nanocomposite production method, electronic device barrier structure and OLED including barrier structure

摘要

The present invention relates to a nanocomposite comprising primary nanoparticles of a particle size of less than 10 nm forming a mass with a bimodal size distribution dispersed within a polymer matrix. Here, the nanocomposite includes 10 to 80% by weight of a lump having a particle size of less than 30 nm and 20 wt. Of a lump having a particle size of 100 nm or more (preferably 400 nm or more), based on the total weight of the lump. Contains less than%. The surface of the nanoparticle may be modified with a surface modifier. This composite can advantageously be used in a high refractive barrier structure for electronic devices such as organic light emitting diodes (OLEDs) as an organic layer between two inorganic layers.
