Abstract :

With the aim to orienting WS2 nanotubes in molten polymer phases by application of a magnetic field, a new synthetic strategy was used to decorate the surface of WS2 nanotubes with FeWO4 nanoparticles. Nanoparticles FeWO4 were obtained by depositing amorphous iron oxide film onto surface of the WS2 nanotubes with subsequent high temperature annealing. Some different phases are forming during the process of phase transformations and they definitely manifest themselves by their different magnetic properties. The nanotubes could be oriented by moderate magnetic field (0.3 T) in low viscosity fluids like ethanol.
