A material which comprises a polyrotaxane and a polymer and is crosslinked by irradiation with light. In the material, which comprises a first polyrotaxane and a polymer, the first polyrotaxane comprises first cyclic molecules, a first linear molecule with which the first cyclic molecules are clathrated in a spitted state, and first blocking groups disposed respectively at both ends of the first linear molecule so as to prevent the first cyclic molecules from being released from the first linear molecule. The first polyrotaxane combines with at least part of the polymer through the first cyclic molecules by photocrosslinking reaction.

La présente invention concerne un matériau comprenant un polyrotaxane et un polymère et qui est réticulé par irradiation à la lumière. Dans le matériau, qui comprend un premier polyrotaxane et un polymère, le premier polyrotaxane comprend des premières molécules cycliques, une première molécule linéaire avec laquelle les premières molécules cycliques sont clathratées en un état diffus et des premiers groupes de blocage agencés respectivement aux deux extrémités de la première molécule linéaire de sorte manière à prévenir les premières molécules cycliques de toute libération depuis la première molécule linéaire. Le premier polyrotaxane se combine à au moins une partie du polymère par le biais des premières molécules cycliques par une réaction de photoréticulation.
