Title:
COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR, AND QUANTUM DOT LIGHT-EMITTING DIODE
Document Type and Number:
WIPO Patent Application WO/2022/143676
Kind Code:
A1
Abstract:
Disclosed are a composite material and a preparation method therefor, and a quantum dot light-emitting diode. The composite material comprises zinc oxide nanoparticles and polypyrrole coated on the surface of the zinc oxide nanoparticles. In the composite material of the present disclosure, the polypyrrole coating can effectively increase the spacing between the zinc oxide nanoparticles, passivate the surface of the zinc oxide nanoparticles and reduce the generation of oxygen vacancies, and the polypyrrole coating can also protect the zinc oxide nanoparticles from agglomeration. N and C atoms are present on the surface of pyrrole, and can effectively provide an electronic transport path and improve the electronic transport capability. The polypyrrole coating can also effectively isolate the erosion of the zinc oxide nanoparticles by water and oxygen, and the compactness of polypyrrole is higher than that of a common ligand.
