摘要

本研究目的為藉由改變4,4'-二苯甲基二異氰酸鹽(4,4'-diphenylmethane diisocyanate, MDI)/聚己內酯二元醇(polycaprolactone diol, PCL diol)/1,4-丁二醇(1,4-butanediol, BDO)等不同莫耳比製備形狀記憶型聚氨基甲酸酯(Shape Memory Polyurethane, SMPU)；並探討改變不同單體莫耳比及添加不同濃度奈米銀溶液對其物性及形狀記憶性的影響。經由實驗發現，隨著硬鏈節含量的增加，SMPU熱裂解溫度及軟鏈節熔點皆會明顯的下降。在添加奈米銀方面，會造成SMPU的強力、延伸比下降，而形狀記憶能力亦會下降，但少量奈米銀卻能有效提升形狀記憶能力。

In this article, we have been investigated that synthesizing and properties of shape memory polyurethane (SMPU). The shape memory polyurethane was synthesized from PCL diol (polycaprolactone diol), MDI(4, 4'-diphenylmethane diisocyanate) and BDO (1,4-butanediol) in this experiment. We analyzed that the effect of differential mole ratio of monomers to synthesized SMPU. Besides, the various concentrations of Nano-silver were mixed with SMPU. Mechanical properties and shape memory behavior of SMPU nanocomposite films were investigated. As a results, degradation temperature and soft segment crystal melting temperature of SMPU decrease with the content of hard segment increase. When SMPU mixed Nano-silver, the strain and stress of SMPU nanocomposites and shape memory ability will be decrease with increasingconcentrations of Nano-silver, whereas mixed a low concentration of Nano-silver will improve shape memory effect.
