Abstract : This poster presentation highlights the development of Graphene Oxide nanocomposites integrated by ferroelectric PLZT for energy, sensors and actuator, and biomedical smart (both sensing and actuating) applications. The Graphene Oxide (GO) reduced by PLZT were synthesized and characterized for phase formation and nanostructure, dielectric and piezoelectric properties. PLZT was prepared by mixed oxide method and nano powders by ball mill, while GO and FGO (i.e., PLZT integrated GO) nanocomposites were prepared by Hummer’s method. Predominantly, tetragonal phase was witnessed in pure PLZT. GO could enhance surfacial properties. In other words, on one hand GO enhances large surfacial contributions to the prototype due to its 2D flakes supporting to functionalized PLZT particles, on the other hand, GO’s interaction with hosts’ β phase piezoelectric nature resulting in competitive piezoelectric properties. The piezoelectric charge coefficient d33 = 197x10-12C/N for pure PLZT whereas FGO had shown 218 x10-12C/N were found in these nanocomposites, which could be possible candidates for energy, sensors and actuator and biomedical applications. Index Terms- Biomedical applications, Graphene Oxide, Ferroelectric PLZT, dielectric and piezoelectric properties.
