Nanocomposites structures based on the electrochemical assembling of zinc oxide nanorods and carbon nanotubes

► Hydrodynamic regime has been fundamental to address carbon nanotubes towards electrode surface being trapped by ZnO nanorods growing process. ► Pressure method have made possible to obtain SWCNTs paper proper as working electrodes. ► SWCNTs showed better electrical properties as both substrate and once is ZnO contacted when is compared with MWCNTs.
