MULTILAYER STRUCTURE COMPRISING A LAYER OF SUPRAMOLECULAR MATERIAL AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a multilayer structure comprising at least one layer of supramolecular material and one layer of rigid material, to a method for producing such a structure by casting a composition comprising a precursor of the supramolecular material, and to the uses of the structures produced, especially for applications where a dampening of impacts, vibrations and/or sound waves is desired, for example for producing locomotion vehicles such as automotive, rail, nautical, aeronautical or aerospace vehicles, or for the construction industry.

主权项

1. A multilayer structure comprising at least two contiguous layers, referred to as first and second layers, the first layer comprising at least one rigid material and the second layer comprising at least one supramolecular material, said supramolecular material comprising arborescent molecules each comprising at least difunctional fragments and at least trifunctional fragments linked to one another by ester or thioester bridges, alone or in combination with amide or urea bridges, said bridges being formed from two functional groups carried by different fragments, said molecules additionally comprising, on the fragments located at the ends of the arborescences, end associative groups capable of associating with one another via hydrogen bonds and covalently connected to the functional groups not participating in said bridges.
