Abstract
In the current paper, tungsten disulfide hollow spheres modified by methyltrioctylammonium chloride with diameters of about 200 nm have been successfully prepared through a solvothermal process. The products were characterized by X-ray power diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, scan electron microscopy and high revolution transmission electron microscopy, respectively. The tribological properties of the as-prepared WS2 in liquid paraffin (LP) were studied and compared with those of commercial colloidal MoS2 (CC-MoS2). The worn surfaces were analyzed by XPS and SEM. Results show that the as-prepared WS2 hollow sphere is a better anti-wear and friction-reducing additive in LP than CC-MoS2.
