2. Technical description of the innovation
-
The synthesis of purely inorganic macro-mesocellular materials was first reported by F. Carn et al. and named Si(HIPE), HIPE standing for High Internal Phase Emulsion . This synthesis is based on the use of a concentrated direct emulsion (oil-in-water) and surface-active molecules dissolved within the aqueous phase, inducing both stabilization of the oil/water interface and structuring of the aqueous volume via the formation of giant micelles. Typically, 5 g of tetraethoxysilane (TEOS) are added to 22 mL of a 25% by weight aqueous...
