The present invention relates to a method for producing a porous material comprising the steps of: providing a mixture (I) comprising a water-soluble polysaccharide, at least one compound suitable for reacting as a crosslinking agent for polysaccharides or releasing a crosslinking agent for polysaccharides, (A) at a pressure in the range of 20 to 100 bar, comprising exposing the gel to carbon dioxide for a time sufficient to form the gel (A), and depressurizing the gel (A) And more particularly, Thereafter, the gel (A) is exposed to the water-miscible solvent (L) to obtain a gel (B), which is then dried. The present invention further relates to a porous material obtainable in this manner, and to the use of the porous material as an insulating material, or for cosmetic, biomedical or pharmaceutical uses. |
