| Abstract |
The thermal shape memory behavior of a series of amino acid-based poly(ester urea)s is explored. We demonstrate that these materials exhibit excellent shape memory performance in dual- and triple-shape thermomechanical testing over a range of amino acids and chain extender lengths. The mechanism of shape transformation and recovery is attributed to activation of chain mobility above the glass transition temperature as well as a strong hydrogen bonding network. Additionally, we demonstrate that we can tune the shape memory properties of these materials with polymer blending, enabling quadruple-shape memory cycles. The significance of these findings will be discussed in relation to other biodegradable shape memory polymers and to relevant biomedical applications. |
