Title:
THREE-DIMENSIONAL POROUS STRUCTURE AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/149451
Kind Code:
A1
Abstract:
The present invention relates to a three-dimensional porous structure and a fabrication method therefor. A method for fabrication of a three-dimensional porous structure according to the present invention comprises the steps of: coating the surface of a combustible organic particle with a coating material including coal ash to form a core-shell particle comprising a combustible organic particle core and a coating shell covering at least a part of the combustible organic particle surface; mixing a plurality of the core-shell particles with an organic or inorganic binder to form a three-dimensional structure in which the core-shell particles are conjugated and connected to each other; and thermally treating the three-dimensional structure, wherein at least a part of the combustible organic particle in the core-shell particle is lost in the step of thermally treating the three-dimensional structure to form a hollow part within the core-shell particle and a plurality of micropores in the coating shell.
