Shape-memory effect by amorphous polymers blending |
| 초록 |
Shape-memory polymers have the ability to return from a temporary shape to a permanent shape by external stimuli such as temperature. The aim of this study is to investigate biodegradable polymers with shape-memory property through polymer-blend method and to characterize their shape-switching in body temperature (37oC). In this study, some biodegradable polymers were dissolved in chloroform and film samples of various ratios were prepared by solution casting. The shape-memory properties were characterized using dynamic mechanical analysis. The polymer blend showed good performance of shape-fixity and shape-recovery based on glass transition temperature as a function of blend ratio. It is expected that this polymer can be potentially used in vascular closure device and fully biodegradable stent. |
