Tunable Shape Memory Polymers from α-Amino Acid-Based Poly(ester urea)s
The thermal shape memory behavior of poly(ester urea)s (PEUs) composed of varying α-amino acids and linear diols has been explored. The thermal, mechanical, and shape memory properties of PEUs are shown to be controlled by changing the amino acid and diol components of the polymer, without negatively affecting the shape memory performance of the polymer in most cases. These materials display triple-shape memory behavior and temperature memory properties due to a broad glass transition temperature interval. The versatility of the shape memory behavior of PEUs was explored by demonstrating shape transformations of thin films, salt leached scaffolds, and larger constructs. Overall good shape memory behavior in combination with the tunable properties of PEU materials makes them prime candidates for use as shape memory materials in biomedical applications.
