Abstract
The elasto-mechanical and transport properties of HTSC YBCO/polyacrylonitrile (PAN) composites have been investigated. The results indicate clearly the effect of PAN presence on the porosity, microstructure, crack-stability and toughness, and grain-surface pinning strength. At 35% PAN fraction an extensive bridgelike linking network develops, which results in a dramatic increase of the crack-stability and an increased fluxon mobility. In contrast to other reported SC/polymer systems, the YBCO/ PAN composite exhibits a transport current resistive transition even at relatively high PAN concentration. A comparison of finegrain and coarse-grain YBCO ceramic characteristics allows a better understanding of the role played by the PAN host.
