摘要： 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.

摘要： An absorbent article comprising an absorbent member positioned between a topsheet and a backsheet is provided. The absorbent member contains at least one layer that comprises porous superabsorbent particles, wherein the particles exhibit a relative humidity microclimate of about 67% or less after being exposed to an atmosphere having a temperature of about 23°C and relative humidity of 80% for a time period of 20 minutes.
