| abstract |
The present invention relates to a method for preparing a porous material, the method comprising at least: providing a mixture (I) comprising a composition (A) and a solvent (B), the composition (A) comprising components suitable for forming an organogel; reacting the components in composition (A) to form a gel in the presence of solvent (B); and drying the gel obtained in step b), wherein composition (A) comprises catalyst (C), the catalyst (C) is selected from alkali metal salts and alkaline earth metal salts of saturated or unsaturated monocarboxylic acids having 4 to 8 carbon atoms. The invention also relates to the porous material obtainable by this method, and to the use of said porous material as thermal insulation material and in vacuum thermal insulation panels, in particular internal or external thermal insulation systems. |
