ABSTRACT
A novel technique for preparing YBCO/polymer composites showing true superconducting transition above liquid nitrogen temperature has been developed. A thermoplastic polymer, poly(methyl methacrylate) (PMMA), was used to improve the flexural properties of the high-temperature superconducting ceramic YBCO. The superconductor/polymer composites exhibited superconducting resistive transition at about 90 K. The scanning electron micrograph reveals excellent wetting, infiltration, and polymerization of the monomer into the superconducting material. Polymer impregnation has no measurable effect on the critical transition temperature, the width of transition, and Meissner effect.
