The result TiO2 nanorings were characterized by FE-SEM and XRD. Results showed that the inner diameter of the TiO2 nanorings matched size of the polystyrene nanospheres used, and the thickness with nanometer size depended on that of the TiO2 gel coated on the PS surface.展开更多

The antiwear ability of the oleate/PSt/TiO 2 nanospheres as additives in base oil was evaluated. The results indicate the oleate/PSt/TiO 2 nanosphere composites have good wear and extreme pressure resistance.展开更多
