Title:
POROUS MEMBRANE AND METHOD FOR MANUFACTURING POROUS MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2023/074670
Kind Code:
A1
Abstract:
One aspect of the present invention relates to a porous membrane having a porous structure, the porous membrane being characterized in that at least the porous structure of the membrane cross-section is observed in a cross-sectional surface cut at a discretionary cross-section in which at least the porous structure of the porous membrane can be observed, and, when fractal dimensions calculated using image data obtained by capturing an image of the porous structure at a discretionary image-capture position and a discretionary image-capture magnification are calculated under a plurality of conditions numbering at least two or more, all of the fractal dimensions calculated under each of the plurality of conditions are 1.5-1.9 (inclusive).
