Title:
PREPARATION METHOD AND APPLICATION OF PEROVSKITE QUANTUM DOT POLYMER MICROSPHERE HAVING CORE-SHELL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/179456
Kind Code:
A1
Abstract:
The present invention relates to the technical field of perovskite quantum dots, and in particular, to a preparation method and application of a perovskite quantum dot polymer microsphere having a core-shell structure. According to the present invention, a polymer microsphere having a three-layer core-shell structure is prepared by a ternary coaxial electrostatic spraying method, perovskite is generated in situ on a core layer of the polymer microsphere after a solvent is dried, and different types of polymer materials are selected as core-shell layers to block water and oxygen, so as to improve the aging stability of perovskite quantum dots. The synthesized perovskite quantum dot polymer microsphere having a core-shell structure can be dispersed into conventional photocuring or thermosetting glue to prepare a perovskite quantum dot film, which is applied to a backlight module for wide-color-gamut liquid crystal display.
