Shape Memory Properties

Novel stereocomplexed physical hydrogels with tunable crystallizability and high strength were prepared. The microstructure, swelling behavior, and mechanical and shape memory properties of the obtained hydrogels can be tailored by varying the copolymer composition and crystallinity of the stereocomplex.
