在这项工作中，研究了纳米粘土（1-4 wt %）和偶联剂（2和4 wt %）负载对纳米复合材料物理力学性能的影响。以聚丙烯（PP）、甘蔗渣粉和纳米粘土（蒙脱土型）为基材，经熔融复合后加压成型制成复合材料。当纳米粘土添加量为1 ~ 3 wt %时，拉伸性能显著提高，但随着纳米粘土添加量增加到4%，拉伸性能略有下降。当纳米粘土添加量为1wt %时，冲击强度降低6%，当纳米粘土添加量从1%增加到4%时，冲击强度进一步降低。最后，随着纳米粘土含量的增加，PP/甘蔗渣复合材料的吸水率降低。此外，偶联剂4 wt %的MAPP比2 wt %的MAPP更能改善复合材料的机械和物理性能。从这些结果中，我们可以得出结论，纳米粘土的加入可以使传统复合材料获得更好的物理和力学性能。©2009 Wiley期刊公司高分子学报，2009
In this work, the effects of nanoclay (1–4 wt %) and coupling agent (2 and 4 wt %) loading on the physical and mechanical properties of nanocomposites are investigated. Composites based on polypropylene (PP), bagasse flour, and nanoclay (montmorillonite type) was made by melt compounding and then compression molding. When 1–3 wt % nanoclay was added, the tensile properties increased significantly, but then decreased slightly as the nanoclay content increased to 4%. The impact strength was 6% lower by the addition of 1 wt % nanoclay, it was decreased further when the nanoclay content increased from 1 to 4%. Finally, the water absorption of PP/bagasse composites was lowered with the increase in nanoclay content. Additionally, the coupling agent, 4 wt % MAPP, improved the mechanical and physical properties of the composites more than the 2 wt % MAPP. From these results, we can conclude that addition of nanoclay enables to achieve better physical and mechanical properties in conventional composites. © 2009 Wiley Periodicals, Inc.
