ABSTRACT

Through the development of nanotechnology it has been widely studied the morphology and size control in nanopowders synthesis. However, most of these techniques are successful to synthesize nanopowders in a small scale. In this research, a large semi-industrial scale synthesis method is proposed, named continuous arc discharge in controlled atmosphere (DARC-AC). Using this technique, it is possible to directly obtain clean nanostructures (low amount of impurities) with more than 90% of particles below 100 nm. In this study, the method utilizes metallic zinc and oxygen as precursors in order to produce ZnO. The ZnO nanopowders were incorporated in a thermoset polymer (epoxy resin) to study their influence on the thermo-mechanical properties of the matrix. As main results, the mechanical properties of the nanocomposite epoxy/ZnO nanoparticles (ZnO-NPs) do not differ from the original properties of the epoxy resin. Nevertheless, thermal behavior, conductivity, and diffusivity properties of the nanocomposite are improved. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43631.
