Bi2Sr2CaCu2O8+x (Bi-2212) nanowires were fabricated employing electrospinning. The subsequent thermal treatment is necessary to obtain the final crystal structure and superconductivity. The final average diameter of the nanowires is around 100 nm and the overall length can reach up to 100 µm according to the electron microscopy. Phase and crystallization information is given by X-ray diffraction and transmission electron microscopy. In order to obtain elongated and parallel nanowires, a SiO2/Si wafer containing a narrow slit is employed as target. This new preparation approach of high-temperature superconductor nanowires may provide several advantages in the subsequent electric and magnetic measurements of the superconducting properties.
