摘要： 利用聚偏氟乙烯（PVDF）微小结晶的物理交联点作用，制备了形状记忆性能优异的聚偏氟乙烯/丙烯酸酯聚合物（PVDF/ACM）共混材料。 为提高其形状回复应力，又将碳纳米管（CNT）引入该共混体系中，系统研究了PVDF/ACM/CNT三元体系纳米复合材料的制备、结构及性能。 结果表明，碳纳米管在PVDF/ACM体系中分散均匀；在基本保持其形状记忆性能的前提下，加入质量分数为4%的CNT，材料在25 ℃时的储能模量由2000 MPa提高至3130 MPa。

Abstract: Shape memory poly(vinylidene fluoride)/acrylic(PVDF/ACM) blends, in which tiny crystals of PVDF serve as the net points, were fabricated. Furthermore, carbon nanotubes(CNTs) were introduced to enhance the shape recovery properties. Fabrication, structure and performance of nanocomposites were investigated systemically. Our results show that PVDF and ACM are miscible, and the CNTs are all well dispersed. The resultant storage modulus of the shape memory materials is improved remarkably from 2000 MPa to 3130 MPa at 25 ℃, while the shape memory performance of them remains stable.

Key words: CNTs, Nanocomposite, Microcrystal, Shape Memory Polymer (SMP)
