Abstract
An absorbent article containing a composite mixture of absorbent macroporous particles and binder particles. Preferably, the absorbent macroporous particles are those having a macroporous structure which allow for the rapid flow of liquid therein, e.g., aerogels, xerogels, cryogels, or mixtures thereof. The absorbent articles produced thereby are preferably thin and lightweight, but maintain an ample rate of absorption allowing for a more rapid uptake of higher volumes of liquids.
Claims13

- contacting an absorbent article with a liquid, wherein said absorbent article comprises a first substrate and a laminate, wherein said laminate comprises a mixture of binder particles and absorbent macroporous particles, thereby absorbing said liquid within said absorbent macroporous particles;
- wherein said absorbent macroporous particles are selected from the group consisting of:
- aerogels, xerogels, cryogels, and a combination thereof.
