Abstract

The authors have prepared poly(vinylidenefluoride-trifluoroethylene) Ni/P(VDF-TrFE) nanoscaled coaxial cables with Ni nanowires as the cores and P(VDF-TrFE) nanotubes as the shells by a two-step process. Scanning electron microscope and x-ray diffraction measurements revealed the microstructure and crystallinity of the nanocables. Electrical measurements indicated that the nanocables possessed a large specific capacitance (∼ 10.84 pC/mm2) and ferroelectric remnant polarization (∼ 10 μC/cm2) due to the composite structure. The distribution of electrical field in the nanostructure was also analyzed.
