Abstract: An absorbent article includes an absorbent member positioned between a topsheet and a backsheet. The absorbent member contains at least one layer that includes superabsorbent particles containing a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 60 darcys or more, or of 90 darcys or more.

Abstract: Superabsorbent particles have a median size of from about 50 to about 2,000 micrometers and contain a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 20 darcys or more, of 30 darcys or more, of 60 darcys or more, or of 90 darcys or more. A method for forming such superabsorbent particles includes forming a composition that contains a superabsorbent polymer and a solvent system; contacting the composition with a non-solvent system to initiate formation of the porous network through phase inversion; removing non-solvent from the composition; and surface crosslinking the superabsorbent particles.

Abstract: The present disclosure is directed to a closed cell foam matrix for delivering oxygen containing a superabsorbent material oxygen entrapped within the superabsorbent material. The superabsorbent material has at least 15 percent by mass monoethylenically unsaturated carboxylic, sulphonic or phosphoric acid or salts thereof, an acrylate or methacrylate ester that contains an alkoxysilane functionality, and a copolymerizable hydrophilic glycol containing ester monomer. To produce the closed cell foam matrix for delivering oxygen, an alkali hydroxide catalyst is added to the superabsorbent material to form a hydrogel layer. Then, an oxygen precursor is added to the hydrogel layer. The hydrogel layer is heated to produce oxygen by reacting the alkali hydroxide catalyst and the oxygen precursor thereby entrapping the oxygen in the formed closed cell foam matrix.
