The unusual electrical and mechanical properties of carbon nanotubes (CNTs) have motivated a flurry of interests to exploit their applications in advanced composite materials, particularly in polymer composites, to improve the performance of a matrix or to achieve new properties. Shape memory polymer (SMP) as one of smart materials was characterized by the recoverability of shape memory effect, but its mechanical property such as the strength wasn't strong enough. In this study, CNT/SMP nanocomposites were developed with the vapor growth carbon fibers (VGCFs). The specimens with different VGCF weight fraction, such as SMP bulk, 0.5wt%, lwt% and 1.5wt%, were prepared, and their mechanical properties were investigated. The recovery behavior and recovery stress of CNT/SMP nanocomposites were also clarified.
