A novel supramolecular shape memory material based on partial α-CD-PEG inclusion complex

A novel supramolecular shape memory material was prepared based on partial α-CD-PEG inclusion complex, which contains α-CD-PEG inclusion crystallites as a fixing phase and naked PEG crystallites as a reversible phase. The recovery ratio of these materials could reach 97%. The characteristics of the material were investigated and a mechanism for the shape memory behavior was proposed.
