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..

Key words: Macromer, Polypseudorotaxane, In-situ polymerization, Supramolecular-structured hydrogel
