The present invention relates to a method for preparing porous silicone materials. In particular, the present invention relates to a method for the preparation of a porous silicone material, comprising the steps of: 1) preparing a direct emulsion E of silicone-in-water, the direct emulsion E comprising: A) by polyaddition or polycondensation Crosslinked silicone binder A; B) at least one nonionic silicone surfactant B having a cloud point of 10°C to 50°C, preferably 15°C to 45°C; C) optionally, at least one catalyst C; and D) water, 2) heating the emulsion E to a temperature greater than or equal to 60°C to obtain a porous silicone material; and 3) optionally, drying the porous silicone material, preferably by heating . |
