摘要：

A multistimuli-sensitive shape memory hydrogel with dual and triple shape memory properties,was prepared by grafting dansyl groups into the network of polyacrylamide (PAAM). The hydrophobic aggregation of dansyl groups acted as molecular switches, which showed reversible aggregation-disaggregation transition in aqueous solution in response to the pH or temperature change.
