Document Type and Number:
WIPO Patent Application WO/2020/151607
Kind Code:
A1
Abstract:
Disclosed are a composite microsphere having a radial fibrous mesoporous shell layer/hollow core layer structure and a preparation method therefor. The composite microsphere has a cavity, a core layer and a mesoporous shell layer, wherein the mesoporous shell layer has radial fibrous mesoporous channels. The preparation method for the composite microsphere comprises: preparing styrene microspheres; mixing the styrene microspheres, a first emulsifier, water, and an alcohol dispersant and uniformly dispersing same, adding an alkaline regulator to adjust the solution to alkalinity, and adding a first material for a first polymerization reaction to obtain a first reaction mixture; adding a second emulsifier and an organic solvent, uniformly mixing same, and then adding a second material for a second polymerization reaction to obtain a second reaction mixture; and centrifuging the second reaction mixture, washing and drying same to obtain the composite microsphere.
