Poly (vinylidene-difluoride) (PVDF) composite films with homogeneously dispersed Bi{sub 4}Ti{sub 3}O{sub 12} nanoparticles were synthesized by spin coating method from mixed solvent solutions. The effects of ferroelectric nanoparticles loading on the formation of α, β and γ phases of PVDF were studied using X-ray diffraction, infrared and Raman spectroscopy. The amount of the ferroelectric β and γ phases present in the composite films was found to increase with increased nanoparticles loading. We have shown that the formation of electroactive phases of PVDF with extended chain conformations can be enhanced by the addition of a well-dispersed nanoparticles loading.
