| 英文摘要 | New novel kinds of thermosensitive hydrogels with supramolecular structures were synthesized by reversible addition fragmentation chain transfer (raft) polymerization of n-isopropylacrylamide ( nipam) and polypseudo rotaxanes in the presence of n,n-methylenebisacylamide (bis) as a cross-linker. the polypseudorotaxanes were prepared by supramolecular self-assemblies of alpha-cyclodextrins threaded onto (4a-peg) polymers. the structure of the hydrogels were characterized in detail with ftir techniques. the analytical results demonstrated that a channel-type crystalline structure of inclusion complexes (ics) remains in as-obtained hydrogels. their swelling behavior was measured gravimetrically in the temperature range from 20 to 60 c. the supramolecular structured hydrogels by raft polymerization ( raft gels) showed accelerated shrinking kinetics to conventional hydrogel (cg), surprisingly. |
