One aspect of the present invention includes a swellable sol-gel composition including a plurality of interconnected organosilica nanoparticles. Another aspect of the present invention includes a swellable composite including a plurality of interconnected organosilica nanoparticles and a particulate material capable of binding to or reacting with a non-polar or organic sorbate. When dried, the sol-gel composition and the swellable composite may be capable of swelling to at least twice their dried volume when placed in contact with a non-polar or organic sorbate. |
