摘　　要：将丙三醇与己内酯通过开环聚合得到多臂形聚己内酯(MPCL),并将MPCL、HDI与Azoba通过溶液聚合的方法合成具有光-热双重响应的多臂形状记忆聚氨酯(MAPU)。合成的MAPU具有明确的支化结构,刺激方式多样、定点性和可远程操作等特点,既增加了形状记忆材料的功能性,又增强了其形状记忆响应性能。In this paper,MPCL is prepared by ring-opening polymerization of glycerol and caprolactone.And then,a new structure of multiarm shape memory polyurethane(MAPU)with photo-thermal dual response is synthesized by solution polymerization of MPCL,HDI and Azoba.Based on the characteristics of clear branching structure,diversified stimulation modes,fixed point and remote operation,the function of shape memory materials and the shape memory response performance are enhanced.
