Absorbent compositions with clay aerogels and methods for forming absorbent compositions
First Claim
1. An absorbent composition, comprising:
- particles of an absorbent porous clay aerogel comprising one or more of (a) an aerogel component derived from at least a clay and one or more of (i) a (co)polymer and (ii) binder component and (b) a clay aerogel-based porous ceramic derived from at least the aerogel component; and
an additive material in contact with at least one clay aerogel particle and comprising one or more of a clumping agent, an antimicrobial agent, a pH-adjusting agent, a fragrance, a deodorant, an odor-control agent, a coloring agent, a dedusting agent, a urease inhibition agent and a non-aerogel absorbent material.

Abstract
Lightweight, highly absorbent compositions including clay aerogels are suitable for use in the home as well as in industry and have particular suitability for use as animal litter. The compositions can further include components, for example as part of the mixture and/or as a coating on a surface of the clay aerogel component, that have properties, for example, that aid in malodor reduction, clumping, or the like, or combinations thereof. Also, clay aerogel polymer composites, formed from various types of clay and (co)polymers, which are relatively low density materials having myriad applications are disclosed. Numerous methods for preparing the clay aerogel polymer composites are disclosed.
