Abstract

Facing the global problem of the energy crisis and the concern about the impoverishment of energy sources, emerge a need of the energetic area research, with alternatives that improve the device performance and reduce or replace the feedstock used currently, with lower cost and greater sustainability. In this context, the nanotechnology appears with goal of produce new materials that can be used to be applied in several systems, became more efficient economic and high performance. The nanomaterials more used to applied in energy storage device are transition metal oxides, conducting polymers and carbon derived materials. These structures, when combined, they present an even greater performance, occasioned by interaction and synergism between the components. Therefore, this work proposes the synthesis and characterization of a novel nanocomposite, based on transition mixed metal oxide, with confinement 2D, RuxWyOz, and a conductive polymer, that is polyaniline. The obtaining of mixed oxides two-dimensional is still great challenge for science, being treated, therefore, in an embracing area for further research. Furthermore, the combination of RuxWyOz/Polyaniline, will allow not only increase the efficiency of the system, but also the obtaining of the flexible device, being able be used substrates without conductive properties, as PET, due a high conductivity of the polymer utilized. The methodologies showed in this work will be innovative, relatively simple and applicable at any laboratory. Will be used too, several techniques of characterization of materials, searching explore and understand the properties of this novel binary nanocomposite. (AU)
