High-temperature superconducting nanocomposites and their stability

摘要

We synthesized composites based on high-temperature superconducting ceramics YBa₂Cu₃O_6.91 (Y123) with polymer additives poly(ethylene glycol) dimethacrylate (poly(EGDMA)). We studied the effect of additives in the obtained nanocomposites on processes of their degradation under the action of steam and water at various temperatures as well as changing phase composition and electro-physical characteristics of organic high-temperature superconducting composites. It is shown that application of organic polymer increases Y123 ceramics stability and does not effect considerably on their temperature of transition to the superconducting state.
