Abstract
In a method of making an absorbent composite, a porous, stabilized structure is formed and impregnated with a flowable superabsorbent precursor. The flowable superabsorbent precursor is cross-linked to form a superabsorbent material within the stabilized structure. The surface area of one of the flowable superabsorbent precursor impregnated with the stabilized structure and the superabsorbent material formed within the structure is increased. In one embodiment, the surface is increased by freeze drying the impregnated structure.
