Title: Semiconductor nanoparticle with hydrophobic side chain ligand-polymer nanocomposite, preparation method thereof and optoelectronic device comprising the same
Inventor: KANGTAEK LEE
IPC: C08K9/08
Filed: 2019-09-05
Abstract: The present invention relates to a semiconductor nanoparticle having a hydrophobic side chain ligand-polymer nanocomposite, a method for preparing the same, and an optoelectronic device including the same. Particularly, the surfaces of the semiconductor nanoparticles to which hydrophobic side chain ligands are bound are encapsulated with an amphiphatic polymer, and a matrix polymer is crosslinked by using the amphiphatic polymer on the surfaces of the semiconductor nanoparticles as a crosslinking agent. In this manner, even when a high concentration of semiconductor nanoparticles is used, aggregation of the semiconductor nanoparticles among themselves can be inhibited. In addition, since the amphiphatic polymer directly functions as a crosslinking agent of the matrix polymer, a semiconductor nanoparticle-polymer nanocomposite having high transparency and high light-emitting properties can be obtained without using any additional process, such as UV or thermal curing.
