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: Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.

Abstract: A color-changing polymeric material is provided. The material is formed from a thermoplastic composition containing a continuous phase that includes a matrix polymer, colorant, microinclusion additive, and nanoinclusion additive, wherein the microinclusion additive and nanoinclusion additive are dispersed within the continuous phase in the form of discrete domains. A porous network is formed in the polymeric material when subjected to a deformational strain in a solid state. The polymeric material exhibits a first color prior to being subjected to the deformational strain and a second color after being subjected to the deformational strain, the first color being different than the second color.

Abstract: A delivery system containing an active agent within a polymeric material formed from a thermoplastic composition is provided. Through selective control over the particular nature of the thermoplastic composition, as well as the manner in which it is formed, the present inventors have discovered that a porous network can be created that contains a plurality of micropores and nanopores. The ability to create such a multimodal pore size distribution can allow the delivery rate of an active agent to be tailored for a particular use.
