PREPARATION AND CHARACTERIZATION OF SOME SUPERCONDUCTOR POLYMER COMPOSITES

Abstract

A technique for preparing flexible composites by dispersing high-T(c) bismuth-based superconductor filler in an ABS rubber matrix with transition temperature above 100K (based on magnetization measurements) has been developed. Superconducting tapes or discs of the Bi1.5Pb0.5Sr2Ca2Cu3Ox/ABS composites with flexibility was formed by wet or dry blending. Data obtained from dc resistivity and magnetization measurements on the composites and the features of microstructure are presented.
