Abstract: A mold for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process carried out within the mold can have a lower part defining an interior volume for receiving the precursors of the porous material, wherein the interior volume defines the shape of the body to be manufactured, and at least a first opening through which the body is removable from the lower part. Surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material that is electrically dissipative and non-sticky to a gel formed from the precursors of the porous material and/or the body.

Abstract: A method for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process, including (i) providing a mold, containing a lower part defining an interior volume for receiving the precursors of the porous material, wherein the lower part comprises a first opening, and surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material being electrically dissipative and non-sticky to the precursors of the porous material and/or the body, (ii) filling precursors of the porous material into the lower part in a first inert or ventilated region, wherein the precursors include two reactive components and a solvent, (iii) removing the body from the lower part through the first opening after a predetermined time, (iv) disposing the body onto a support, and (v) removing the solvent from the body.

Abstract: The present invention is directed to a process for preparing a porous material, at least comprising the steps of providing a gel comprising a solvent (S), wherein the solvent (S) has a volume (V1), pressurizing the gel with carbon dioxide at a temperature and a pressure at which carbon dioxide solubilizes in the solvent (S) forming gas-expanded liquid (EL), wherein the gas-expanded liquid (EL) has a volume (V2) and (V2) is greater than (V1); removing supernatant liquid, and drying the gel. The present invention further is directed to the porous material obtained or obtainable according to the process as such as the use of the porous material according to the invention in particular for medical, biomedical and pharmaceutical applications or for thermal insulation.
