The most common approaches for the fabrication of poly(vinylidene fluoride)(PVDF)/ multi-walled carbon
nanotubes(MWNTs) nanocomposites involve solution crystallization and melting crystallization methods. In this study,
PVDF/ MWNTs nanocomposites with varied contents of MWCNTs (up to 0.3wt.%) were prepared via solution
crystallized at 80 °C, solution crystallized at 120 °C and melting at 200 °C. The effect of processing conditions on the
crystal structure, morphology, dielectric and ferroelectric properties of PVDF with the presence of MWNTs was
investigated. It is seen that crystallization temperatures and the concentrations of MWNTs have a synergetic effect of on
the crystal phase and crystallinity of PVDF. Higher crystallization temperatures appeared to be detrimental to the
dispersion of MWNTs in PVDF matrix, however, it was advantage to the growth of crystals and leaded to a higher
degree of crystallinity. Lower crystallization temperatures favored the dispersion of MWNTs in PVDF matrix, which can
effectively promote the formation of polar crystalline β-phase of PVDF. In addition, MWNTs at relatively low content
(<0.1 wt.%) can disperse well in PVDF matrix in different approaches, resulting in high content of -phase and
enhancements in dielectric and ferroelectric properties.
