Low agglomerated tungsten disulfide nanoparticles with mean diameter in range of 20 - 80 nm have been successfully produced by aerosol synthesis method. The particles size was changed by process parameters. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and high revolution transmission electron microscopy (HRTEM). Onion-like structures with interlayer distance of 0.6363 nm was obtained. Polyimide-based composites materials filled by WS2 nanoparticles with different content were developed and its tribological properties were studied. The main application areas for prepared material were determined.
