Abstract: Polyvinylidene fluoride(PVDF)/acrylic rubber(ACM) blends with controlled blend compositions and crystallization conditions exhibit nice shape memory properties. In this work, we systematically investigated the electrical and thermal conductivity of the PVDF/ACM shape memory alloy by the incorporation of multi-walled carbon nanotubes(CNT). It was found that the CNTs are homogeneously dispersed in the polymer matrix. The incorporation of CNTs significantly enhances both the electrical and thermal conductivity of the nanocomposites. The electrical conductivity of the nanocomposites with 4%(mass fraction) CNTs reaches 5000 Ω/square and the thermal conductivity is 0.157 W/(m·K) at 25 ℃.

Key words: CNT,nanocomposites, electrical conductivity, thermal conductivity, shape memory materials
