Abstract

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)
