A material for use in separation, characterized in that it comprises a composite which is composed of a polymer responsive to stimulation and a substance specifically interacting with a substance to be separated and in which the polymer responsive to stimulation undergoes a structural change through a physical stimulation and the change of the polymer causes a change of chemical or physical environments for the interaction of the substance specifically interacting with a substance to be separated, and thus the strength of the interaction thereof with the substance to be separated can be reversibly changed by the change of a physical stimulation, and the polymer responsive to stimulation has no affinity for the substance to be separated.

L'invention concerne un matériau utilisé pour la séparation. Ce matériau se caractérise en ce qu'il comprend un composite comprenant un polymère sensible à la stimulation et une substance interagissant plus particulièrement avec une substance devant être séparée et dans laquelle le polymère susmentionné subit une modification structurelle par stimulation physique. La modification du polymère entraîne une modification des environnements physique et chimique permettant l'interaction de la substance interagissant plus particulièrement avec une substance devant être séparée. De cette façon, la force de l'interaction susmentionnée par modification d'une stimulation physique, le polymère sensible à la stimulation ne présentant aucune affinité avec la substance devant être séparée.
