摘要： Absorbent articles are described comprising an absorbent composite. The absorbent composite comprises a first absorbent layer comprising a polymeric foam having an average cell size of at least 100 microns. The polymeric foam has at least one property selected from a) an indentation force deflection of less than 75 N at 50%; or b) a constant deflection compression set of less than 25% for a deflection of 50%; or a combination of a) and b); and a second absorbent layer in fluid communication with the fluid transport layer. In another embodiment, the a second absorbent layer has an average absorption capacity of at least 20 g/g. In another embodiment, a polyurethane foam is described having an average cell size of at least 100 microns. The polyurethane foam comprises the reaction product of at least one polyol component having polyethylene oxide units and a polyisocyanate component that comprises at least 75 wt-% of at least one polymeric polyisocyanate that lacks urethane linkages. In some embodiments, the polyurethane foam is free of superabsorbent polymer. In some embodiments, the polyurethane foam has an average cell size up to 500 microns. In some embodiments, the polyurethane foam comprises at least 12 wt-% ethylene oxide units. Also described are various composites comprising the polyurethane foam described herein in combination with another substrate such as a second absorbent layer, a fluid impervious backsheet, and/or a fluid pervious topsheet.

摘要： Provided are: a water-absorbent resin which, when used as an absorbent material, retains a high water-absorption performance, increases the diffusivity of a to-be-absorbed liquid and makes it possible to effectively decrease the amount of re-wet; and an absorbent article formed using an absorbent material including the water-absorbent resin. The water-absorbent resin according to the present invention is a water-absorbent resin obtained by polymerizing a water-soluble ethylenically monomer in the presence of an internal-crosslinking agent and thereafter post-crosslinking the polymer with a post-crosslinking agent, characterized in that when subjected to a liquid flow test, the water-absorbent resin has an effective absorbent material index (K) indicated by equation (I) of 250 or greater. Effective absorbent material index (K)=[(the amount of liquid flow) (g)]×[(artificial-urine absorption ratio) (g/g)] (I)

摘要： Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.

摘要： The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). Slippery liquid-infused porous surfaces outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (
