Abstract: An ion-sensitive substance containing a crown ether structure composed of a repeating unit represented by formula (a): —CR1R2—CR3X—O— . . . (a) (in the formula, X is an organic group having an alkoxysilyl group at a terminal, and R1, R2 and R3 are each a hydrogen atom or a hydrocarbon group), and a part or all of the alkoxysilyl groups in the crown ether structure may be hydrolyzed to form a silanol group.

Abstract: The present disclosure provides a method for producing a water permeable molecular sieve in which a porous substrate having micron-size pores has deposited on a surface thereof non-porous 2D platelets to seal, at the substrate surface, pores in the porous substrate to form a layer of 2D platelets. A curable sealing material is deposited onto the layer of 2D platelets and any remaining exposed areas of the surface of the porous substrate and curing the curable sealing material in order to form a sealed layer on the surface of the porous substrate to prevent water by-passing the non-porous 2D platelets and passing through the porous substrate. An array of sub-nanopores are then produced through the sealed layer with the array of sub-nanopores having a size to allow water to pass therethrough but not metal ions to give a water permeable molecular sieve characterized by water permeability at low di□erential pressures.

Abstract: A complex for acid gas separation includes an acid gas separation membrane, a permeated gas flow path member, and a sealing portion. The acid gas separation membrane includes a porous support with pores having an average pore diameter of 0.5 μm or less, and an acid gas separation layer disposed on the porous support. The permeated gas flow path member allows acid gas, which has permeated through the acid gas separation layer, to pass therethrough. The sealing portion seals a region required to be sealed with resin, the region being on the periphery of the permeated gas flow path member and the porous support. The sealing portion is made of epoxy resin, the Tg of epoxy resin is 90° C. or higher and the content of an inorganic filling material is less than or equal to 30% by mass.
