Title:
FILTRATION MEMBRANE FOR TRAPPING MICROPARTICLES, METHOD FOR MANUFACTURING SAME, AND METHOD FOR MEASURING MICROPARTICLE COUNT
Document Type and Number:
WIPO Patent Application WO/2023/203882
Kind Code:
A1
Abstract:
A filtration membrane (1) for trapping microparticles comprises: a base membrane (10) which has communication holes (18, 19, 20) formed therein; and a skin layer (30) which is formed on one surface of the base membrane (10) and in which communication holes (31) are opened. The communication holes (31) in the skin layer (30) are in communication with the corresponding communication holes (18) in the base layer (10). The flow channel diameter of the communication holes (31) in the skin layer (30) is less than the bore diameter of the communication holes (18) in the base membrane (10).
