A study on the fractal behavior of worn surfaces of zinc oxide whisker/natural rubber-styrene butadiene rubber-butadiene rubber composites

摘要

The wear resistance of zinc oxide whisker (ZnOw)/natural robber-styrene butadiene robber-butadiene (NR-SBR-BR) composites has been studied. The result showed that ZnOw modified by coupling agent has a good effect on improving wear resistance of the robber composites. The further investigation shows that the worn surfaces of the composites of ZnOw/NR-SBR-BR appear distinct character of fractal, and the values of both the fractal dimension and the abrasion lots decrease synchronously as the increasing of ZnOw content in the composites.
