Studies on Tetrapod-Shaped ZnO Whisker Modified Polymer Composites
Tetra-needle like ZnO whisker modified NR-SBR-BR and PPS composites were prepared. The outcome of the investigation indicated that T-ZnO had an instinct effect on reinforcing polymer material isotropically. Further analysis showed that experiment results of T-ZnO/PPS composite gave much higher strength than that of the theoretical calculation from classical rule of mixing, and the explanations were put forward. The experimental tests on wear behavior of the composites of T-ZnO/NR-SBR-BR were carried out and got the conclusion that T-ZnO had a good effect of improving the wear resistance. The worn surfaces of the composites of T-ZnO/NR-SBR-BR appeared an instinct character of fractal, and the values of both the fractal dimension and the abrasion loss decreased synchronously as the increasing of T-ZnO loading in the composites.
