Olefinic block copolymer (OBC)/trans-polyoctenamer (TOR) blends with shape memory effect |
초록 |
Shape memory polymer blends were prepared by melt blending of a thermoplastic elastomeric olefinic block copolymer (OBC) and semicrystalline trans-polyoctenamer (TOR). Phase morphology studies and differential scanning calorimetry analysis showed that the blends form immiscible phase-separated structure. Dynamic mechanical analysis of the blends showed a sudden drop in the storage modulus at melting temperature of TOR phase followed by a plateau region till the melting of OBC phase occurs. Such structural features of the blends render them to exhibit thermally triggered shape memory behavior, where OBC contributed to shape recovery and TOR served as a switch polymer in the blend. Effects of blend composition on shape memory behavior (shape fixity and shape recovery) and mechanical properties were investigated. |
