摘要：
A novel supramolecular network has been prepared based on the formation of inclusion complexes between gamma-cyclodextrin and poly(ethylene glycol), in which the PEG chains are interlocked by gamma-CD rings. This PEG/gamma-CD network exhibits good shape memory behavior because of the crosslinked structure. The crosslinked PEG/gamma-CD inclusion complexes and PEG crystallites account for the fixing phase and reversible phase, respectively. The characteristics of the materials have been investigated by H-1 NMR spectroscopy, XRD, DSC, DAAA, viscosity tests, and swelling measurements.
