Abstract
The invention discloses a composite material comprising a deformable gel retained within the pores of a porous rigid support material. In one example of a composite material in accordance with the invention the deformable gel is an organic polymeric material and the support material comprises discrete porous particles of inorganic material. A method for preparing composites in accordance with the invention is also disclosed.

A particulate material comprising a plurality of discrete porous rigid support particles and a deformable xerogel retained within and substantially filling the pore structure of the support particles, said deformable xerogel being capable of sorbing chemical species from solution.
A method for preparing a particulate material comprising a deformable xerogel retained in the pore structure of a particulate porous rigid support material, said xerogel being capable of sorbing chemical species from solution, which comprises introducing a precursor for said xerogel into the pore structure of a plurality of discrete particles of porous rigid support material such that the gel precursor fills the pores of the discrete particles, and effecting gelation of the precursor within the discrete particles to form a plurality of discrete porous rigid support particles having a deformable xerogel retained within and substantially filling the pore structure of the support particles, said deformable xerogel being capable of sorbing chemical species from solution.
