中文摘要	A series of supramolecular inclusion complex (IC) films were formed by threading alpha-cyclodextrin (alpha-CD) molecules over poly(ethylene glycol) (PEG), according to the designed ratio of alpha-CD/PEG. Because of containing alpha-CD-PEG inclusion crystallites as physical crosslinks and uncovered PEG crystallites as "switch phase", the resulting supramolecular alpha-CD-PEG partial ICs displayed a shape memory effect. The properties of the materials were investigated by H-1-NMR, X-ray diffraction (XRD), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and swelling measurement. It was found that the casting temperature, solvent, and the ratio of alpha-CD-PEG inclusion/PEG had great influence on the formation and properties of alpha-CD-PEG partial ICs. The modes of complexes on different conditions were proposed. (C) 2010 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 48: 951-957, 2010
