摘要
以液化M D I和BDO(1,4-丁二醇)为硬段,分别以聚乙二醇(PEG),聚己二酸乙二醇酯(PEAG),聚己二酸丁二醇酯(PBAG),聚己二酸己二醇酯(PHAG),聚己内酯(PCL)为软段合成了聚氨酯形状记忆材料。通过FT-IR,DSC等考察了它们的结构,比较了聚乙二醇聚氨酯(EGPU),聚己二酸乙二醇酯聚氨酯(EAPU),聚己二酸丁二醇酯聚氨酯(BAPU),聚己二酸己二醇酯聚氨酯(HAPU)及聚己内酯聚氨酯(CLPU)的形状记忆性能和力学性能,研究表明,PHAG是液化M D I基形状记忆聚氨酯软段的最佳原料。
The shape memory polyurethane was synthesized based liquidated-MDI and butanediol (BDO) as the hard segment, and poly(butylenes adipate) glycol (PBAG), poly(hexaylene adipate ) (PHAG), poly (ethylene adipate) glycol (PEAG), polyethylene glycol (PEG) and polycaprolactone (PCL) as soft-segment materials. These samples was investigated by meas of using FT-IR, DSC and tested shape memory properties, mechanical properties. It is found that the shape memory polyurethane requires the soft-segments of good crystalline ability. In these materias, the PHAG has a good crystalline ability shape memory properties. It is the best soft-segment material of SMPU.
