Abstract:

PS/TiO2 composite nanospheres were prepared in situ by seed emulsion polymerization, and the structure characterization was carried out by TEM、 UV-Vis、 FTIR、 DSC& TGA. The tribological behaviors of PS/TiO2 nanospheres as additives in paraffin oil were evaluated on a four-ball machine. Experimental results indicate that the PS/TiO2 composite nanospheres have a good anti-wear performance.
