The invention provides nanocomposites comprising a clay and an organic compound, in which the clay is a clay bridged by a metal compound, preferably iron oxide and/or aluminum oxide. The organic compound is preferably a polymer. The clay-based nanocomposites of the invention have good mechanical properties and good heat resistance. The invention also provides cables comprising such a nanocomposite, preferably in their sheath or outer coating. Finally, the invention provides a process for producing said nanocomposite.

Nanocomposite based on a bridged clay, and a cable comprising said composite

The composition comprises: an organopolysiloxane; a polymer material resistant to tearing; a first coupling agent compatible with said organopolysiloxane, and having hydroxyl first functional groups; and a second coupling agent compatible with said polymer and having second functional groups suitable for reacting with said hydroxyl first groups. Application to power accessories and cables.
