Title:
MACROPOROUS STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/085441
Kind Code:
A1
Abstract:
The present invention provides: a mixture which contains a polysaccharide and a block copolymer of a hydrophilic polymer and a polymer having a lower critical solution temperature; a structure which is obtained by removing the block copolymer from the mixture; and a method for producing a macroporous structure, the method comprising a step in which phase separation is caused by mixing a polysaccharide with a block copolymer of a hydrophilic polymer and a polymer having a lower critical solution temperature, and the block copolymer is removed from the mixture after the phase separation.
