Title:
FLUORINE-BASED RESIN POROUS SEPARATION MEMBRANE AND FILTER
Document Type and Number:
Japanese Patent JP2020015002
Kind Code:
A
Abstract:
To provide a fluorine-based resin porous membrane which can simplify a production process, can efficiently capture fine particles, has a high flow rate, prevents clogging, and has a long filtration life.SOLUTION: A fluorine-based resin porous separation membrane is formed of a composite porous membrane which includes a porous base material mainly containing a first fluorine resin and a particle layer that is provided on at least a surface of the porous base material and contains a second fluorine resin having an average particle diameter of 0.01 μm or more and less than 1 μm, in which the first and second fluorine resins are one or more selected from the group consisting of polytetrafluoroethylene, polyhexafluoropropylene and a tetrafluoroethylene-hexafluoropropylene copolymer.SELECTED DRAWING: None
