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.
