Publication number: 20100233112Abstract: A shape memory polymer network may include at least one polymer, a plurality of proton accepting heterocyclic groups, a plurality of proton donating groups, and a plurality of cross-link moieties. At least one of the proton accepting heterocyclic groups and the proton donating groups is attached to the at least one polymer. The network may include an original shape at zero stress, and may include a deformed shape upon subjection to a stress. The network changes from the deformed shape to the original shape upon exposure to an external stimulus.Type: ApplicationFiled: January 15, 2010Publication date: September 16, 2010Inventors: Jinlian Hu, Shaojun Chen
