Document Type and Number:
Japanese Patent JP2021065858
Kind Code:
A
Abstract:
To provide an oil-water separation filtration filter which separates a mixed liquid containing water and oil into a water content and an oil content and enables filtration with a simple constitution at low cost, and an oil-water separation filtration cartridge using the same.SOLUTION: An oil-water separation filtration filter, which passes a mixed liquid containing water and oil, thereby separates an oil content from the mixed liquid and filtrates a water content, includes a water-permeable porous base material including a large number of pores penetrating between one surface to which the mixed liquid containing water and oil flows and the other surface facing the one surface, and an oil-water separation layer formed on an inflow surface side to which at least the mixed liquid in the porous base material flows. The oil-water separation layer has an oil-water separation body containing a fluorine-based compound having an oil-repellency imparting group and a hydrophilic imparting group, and the fluorine-based compound contains one or two or more kinds of compounds among compounds having structures represented by formula (1).SELECTED DRAWING: Figure 1
