Abstract
Poly(vinylidene fluoride) (PVDF) nanocomposites with different content of TiO2 were prepared by melt-intercalation method. The tensile properties of PVDF/TiO2 nanocomposites were greatly improved. The tribological behaviors of the PVDF/TiO2 nanocomposites against steel ring were evaluated on a block-on-ring type (M-2000) wear tester. Nano TiO2 at 1–2 wt.% was effective for improving the tribological properties of neat PVDF, because the nano TiO2 at the low content may act as the reinforcing element to bore load and thus decrease the plastic deformation. The nanocomposite containing 3 wt.% TiO2 exhibited relatively high wear, weak compatibility between nano TiO2 and PVDF may be responsible for the result.
