ELECTRICAL PROPERTIES OF NANOCOMPOSITES

Abstract: A series of carbon nano?ber (CNF)/ polydimethylsiloxane (PDMS)-based nanocomposites was prepared using in situ polymerization technique by critical manipulation of factors, such as method of preparation and chemical modi?cation of ?ller. Quanti?cation of the degree of dispersion was done by introducing a dispersion degree parameter. Ceria-based composites are developed as potential electrolytes for intermediate solid oxide fuel cell applications and a better understanding of the ionic conduction mechanism serves this purpose. Ceria based composites were produced by several processing routes using a ceria-based ceramic host (Sm, Gddoped ceria) and various Na and Li carbonates. Simple ceria/carbonate two-phase nanocomposites were synthesized by the carbonate precipitation method followed by a thermal treatment.
