  • Received Date: 1999-07-23
  • Polystrene(PS)-TiO2 nano-spheres were chemically synthesized. The structure characterization of theprepared PS-TiO2 nano-spheres was investigated by means of transmission electron microscopy(TEM)and Fouriertransform infrared spectroscopy(FTIR). The thermal stability of PS-TiO2 nano-spheres was identified using athermal analyzer(DSC & TGA). The tribological behaviors of PS-TiO2 nano-spheres as additives in paraffin oilwere evaluated on a four-ball machine. The worn surfaces were analyzed with X-ray photoelectron spectroscopy(XPS)also. Experimental results indicate that the PS-TiO2 nano-spheres,under a certain condition,have agood anti-wear performance and improve striking failure load. This is attributed to the formation of a chemical reactionboundary film consisting of TiO2,Fe2O3 and organic fragments.

Abstract: Polystrene(PS)-TiO2 nano-spheres were chemically synthesized. The structure characterization of theprepared PS-TiO2 nano-spheres was investigated by means of transmission electron microscopy(TEM)and Fouriertransform infrared spectroscopy(FTIR). The thermal stability of PS-TiO2 nano-spheres was identified using athermal analyzer(DSC & TGA). The tribological behaviors of PS-TiO2 nano-spheres as additives in paraffin oilwere evaluated on a four-ball machine. The worn surfaces were analyzed with X-ray photoelectron spectroscopy(XPS)also. Experimental results indicate that the PS-TiO2 nano-spheres,under a certain condition,have agood anti-wear performance and improve striking failure load. This is attributed to the formation of a chemical reactionboundary film consisting of TiO2,Fe2O3 and organic fragments.
