Title:
DEGRADABLE MICROSPHERE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/032316
Kind Code:
A1
Abstract:
Provided are a degradable microsphere, a preparation method therefor, and use thereof. The degradable microsphere is formed in a manner that a degradable plastic outer layer is coated with inorganic nanoparticles. The average particle size D50 of the degradable microsphere is 1 μm to 3000 μm. The content of the inorganic nanoparticles is 5 wt % to 15 wt %. The sphericity of the degradable microsphere is greater than 0.86, the particle distribution span is 0.6 to 2.5, the particle distribution is narrow, and the particle fluidity is good. Also provided is a waste-reducing and non-toxic manufacturing method for the biodegradable microsphere.
