| 摘 要： | 1990年, Harada等1,2]首先观察到α-环糊精(α-CD)与PEG形成的结晶包结物(ICs). 进一步的研究发现, n=400～10 000的PEG均能与α-CD形成结晶ICs, 其形成速率与n有关, n=1 000的PEG形成ICs的速率最快. 由于α-CD是通过与相邻α-CD的氢键作用、空间立体配位及其疏水空腔与聚合物链形成包结物, 这种包结物也称为多聚准轮烷. |

| Abstract: | In this paper, the polypseudorotaxanes were synthesized from α-cyclodextrins(α-CDs) threaded onto PCL-PEG-PCL macromers terminated with acrylate groups. Then, supramolecular-structured hydrogels were prepared from the polyseudorotaxanes in a mixed solvent of H2O and DMSO via in-situ polymerization photoinitiated under UV. The structure and properties of the supramolecular-structured hydrogels were characterized by FTIR, TGA and WAXD. The results showed that α-CDs were threaded and immobilized on the network of the hydrogel by rapid photopolymerization, and the feed ratio of α-CDs affected the structure of hydrogels, water absorption, the distribution and states of water, etc.. |
