Percolation of the organic phase in hybrid organic–inorganic aerogels
The properties (texture, mechanical behaviour, etc.) of hybrid organic–inorganic silica aerogels change dramatically when the concentration of the organic additive is varied from a given value. It has been known for several years that this critical concentration is around 40% of the total weight of...

Summary: | The properties (texture, mechanical behaviour, etc.) of hybrid organic–inorganic silica aerogels change dramatically when the concentration of the organic additive is varied from a given value. It has been known for several years that this critical concentration is around 40% of the total weight of silica present in the sample. We have made use of a new structural model to conclude that this concentration of 40% by weight corresponds to the percolation threshold of the organic phase. |
