HIGH T-C SUPERCONDUCTOR POLYMER COMPOSITE BASED ON YBA2CU3O7-X .2. CONDUCTION MECHANISMS AND TEMPERATURE EFFECT ON CONDUCTIVE AND DIELECTRIC PROPERTIES OF POLYPROPYLENE COMPOSITES

摘要

To improve the connectivity of YBaCuO particles in a polypropylene matrix, different amounts of carbon black (N) or copper (C) were incorporated into the binary base system. In this research the effects of these conductor fillers on the conduction mechanism of the experimental composites were studied using complex impedance spectroscopy as the analytical technique. In addition the effects of temperature on certain electrical properties were examined in the synthesized materials. (C) 1995 John Wiley and Sons, Inc. [References: 8]
