通过在聚丙烯酰胺（PAAM）网络中接枝丹磺酰基，制备了具有双重和三重形状记忆性能的多刺激敏感性形状记忆水凝胶。在水溶液中，丹磺酰基团的疏水聚集起到分子开关的作用，在pH或温度变化的作用下，呈现可逆的聚集-解聚转变。
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.
