Abstract
A method for producing polyHIPE porous monoliths, of the polyHIPE type or in the form of a rigid foam, by hardening solutions of condensed tannins in the presence of oil and/or air or in the presence of a non-water-miscible volatile solvent and/or air. Also disclosed is the use of these materials in the areas of catalysis, chromatography, heat and sound insulation, tissue engineering and medication release and as a floral foam.
