Abstract: A method for restoring a programmed article which contains a shape memory composite material of at least one shape memory polymer network with thermally inducible triple shape properties, the method comprising subjecting the article to a magnetic alternating field and simultaneously to an external heat supply in order to trigger the restoration, wherein at least one of the parameters of magnetic field strength (H) and ambient temperature (TUmg) is increased continuously or discontinuously in such a way that the article first experiences a transition in shape from the first temporary shape (TF1) into the second temporary shape (TF2) and subsequently from the second temporary shape (TF2) into the permanent shape (PF).

Abstract: The invention relates to a method for restoring a programmed article which contains, at least over portions, a shape memory composite material, said composite material comprising (i) at least one shape memory polymer network with thermally inducible triple shape properties which comprises at least one first phase-separated switching segment with a first transition temperature (Ttrans,1) and a second phase-separated switching segment with a second transition temperature (Ttrans,2, where Ttrans,1<Ttrans,2) and at least one type of covalent and/or non-covalent netpoints, and ii) a magnetic material embedded in the shape memory polymer, wherein, after a thermo-mechanical programming process, the article being present in a first temporary shape (TF1) and having stored a second temporary shape (TF2) and a permanent shape (PF).
