  • Partitioning member for total heat exchange element, total heat exchange element and total heat exchange ventilator using the partitioning member for total heat exchange element
    Patent number: 9921010
    Abstract: Partitioning member (1) for total heat exchange element includes porous base material (2), and porous base material (2) is filled with hydrophilic polymer compound (3) at a surface and an inside thereof. Hydrophilic polymer compound (3) is formed by polymerizing a low-molecular-weight organic compound having a quaternary ammonium group and an amide group, and represented by chemical formula (1): wherein A is a linear or branched alkylene group having 1 to 10 carbon atoms; R1, R2 and R3 are linear or branched alkyl groups each independently having 1 to 8 carbon atoms; and Y has a polymerizable functional group, and is polymerized to form a main chain of the hydrophilic polymer compound.
