Abstract
The present invention provides a gel containing a water-absorbing crosslinked polymer, and a condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group.
Claims19
A gel comprising a water-absorbing crosslinked polymer, and a condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group, wherein the condensate of the reactive silicon compound and the water-absorbing crosslinked polymer form an interpenetrating network.
An acidic gas separation membrane comprising a gel comprising a water-absorbing crosslinked polymer, and a condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group.
A method for producing a gel comprising a water-absorbing crosslinked polymer, and a condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group, the method comprising forming a second condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group by drying and heating a mixture comprising
- at least one selected from the group consisting of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group, and a first condensate of a reactive silicon compound having at least one selected from the group consisting of an acidic dissociative group, an acidic dissociative group in a salt form, and a derivative group of an acidic dissociative group,
- a water-absorbing crosslinked polymer, and
- water.
