Abstract |
This paper highlights the development of 2D ultra thin Graphene Oxide nanocomposites reduced by relaxor piezoelectric PMN-PZT for biomedical smart (both sensing and actuating). The Graphene Oxide (GO) reduced by (PMNPZT: 0.5Pb(Mg1/3Nb2/3)O3-0.5Pb(Zr0.53Ti0.47)O 3 were synthesized and characterized for phase formation and microstructure, dielectric and piezoelectric studies. PMN-PZT was prepared by coloumbite precursor method while GO and FGO (i.e., PMN-PZT coated GO) nanocomposites were prepared by Hummer’s method. A pseudocubic phase was predominant in pure PMN-PZT. 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 PMN-PZT particles. On the other hand, GO’s interaction with hosts’ β phase piezoelectric nature resulting in competitive piezoelectric properties. The piezoelectric charge coefficient d 33 = 179x10-12C/N for pure PMN- PZT whereas FGO had shown 164 x10-12C/N were found in these nanocomposites, which are suitable for energy harvesting, sensors and actuator applications. Index Terms— Biomedical applications, Graphene Oxide, Relaxer PMN-PZT, Dielectric and Piezoelectric Properties. | |||||||||
