چکیده انگلیسی
This paper presents the synthesis and characterization of BSCCO superconducting fibers synthesized by heat-treating poly(vinyl pyrrolidone) (PVP)/BSCCO precursor microfibers produced by the solution blow-spinning technique. Different concentrations (v/v) of the BSCCO precursor were added to the PVP solution to evaluate the influence of solution viscosity on fiber morphology. The production of PVP/BSCCO microfibers and their morphology were strongly influenced by the volatility of the solvent and the concentration of the added BSCCO in the solution. After heat-treatment, fibrous structures were obtained for the BSCCO system. The structural properties of the samples were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The XRD pattern revealed the formation of Bi2Sr2Ca1Cu2Ox and Bi1,9Sr1,8CuO5,5 phases. Finally, electrical measurements (RÃT) showed electrical resistance decay at the transition temperature (Tc) that was typical of that observed in superconductor materials.
