Title:
複合多孔質イオン交換体の製造方法
Document Type and Number:
Japanese Patent JP4453982
Kind Code:
B2
Abstract:
A composite ion exchanger with ion exchange groups uniformly dispersed therein, comprising a porous polymer having a continuous pore structure, which comprises interconnected macropores and mesopores existing on the walls of the interconnected macropores, having a total pore volume of 1 to 50 ml/g, and a dense layer covering at least one surface of the porous polymer and integrally formed with the porous polymer. The structure provides a body integrally formed from a material functioning as an ion exchange membrane and a material functioning as an ion exchanger and allows the material functioning as an ion exchanger to have an extremely large pore volume and specific surface area. Electric power saving is possible if the product is used as an electrodeionization module for an electrodeionization water purification device.
