Abstract
We will present the one plasma and vacuum reactor methodology for the formation of core@multishell nanowires and nanotubes. This method allows the synthesis of an ample variety of nanoarchitectures combining small-molecules organic nanowires as 1D and 3D soft-templates with the conformal deposition by plasma-assisted methodologies of functional shells including semiconducting oxides as ZnO, TiO2, V2O5, GaOx and Fe2O3 and organic dielectric and semiconducting molecules. A great advantage is high compatibility with the use of different substrates or supports. Hence, NWs and NTs with controlled density, length, and thickness grow from flat processable substrates as TCOs, plasma-treated graphene, laser-treated metals and alloys, metallic meshes, and cellulose filters. In the second part, we will give an overview of the applications of these supported nanostructures for the development of superhydrophobic, anti-icing, and omniphobic surfaces, water-oil separation, photocatalytic water purification, and water splitting. Finally, we will introduce the concept of drop energy harvesting and show the assembly of triboelectric transparent nanogenerators based on semiconducting nanotubes.
