Title:
COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR, AND OPTICAL CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/257701
Kind Code:
A1
Abstract:
The present disclosure provides a composite material and a preparation method therefor, and an optical conversion device. The composite material comprises a lipophilic continuous phase, a first discontinuous phase and a second discontinuous phase that are hydrophilic and dispersed in the continuous phase, and an emulsifier located at an interface of the first discontinuous phase and the continuous phase. The continuous phase comprises at least one lipophilic polymer. The emulsifier is a water-in-oil surfactant. The first discontinuous phase comprises a plurality of microstructures. The second discontinuous phase comprises an oil-soluble wavelength conversion material, and the microstructure comprises a water-soluble protective agent and a dispersion medium for dispersing the protective agent. Since adverse substances such as water and oxygen are preferentially captured by the microstructure after continuing to enter the composite material containing the wavelength conversion material, the wavelength conversion material is protected from being eroded by these adverse substances and fails, thereby improving the stability and the service life of the composite material.
