| 中文摘要: |
| 研究钛酸钾晶须（PTW）与碳纳米管（CNTs）对氟橡胶（FKM）的协同补强作用。结果表明：CNTs在FKM基体中易团聚，分散性较差，而PTW在FKM基体中的分散性较好，当PTW/CNTs并用时表现出协同效应，其胶料的物理性能显著提高；在高温（150 ℃）下，PTW/CNTs并用也表现出协同效应，其胶料的物理性能比单独添加一种填料的胶料好；PTW/CNTs并用填料胶料的压缩永久变形比单独添加PTW的胶料大，但略小于单独添加CNTs的胶料，PTW/CNTs并用对胶料的抗压缩永久变形性能略有改善；PTW/CNTs并用比为4/4时协同效应最好，其补强的胶料物理性能和抗压缩永久变形性能最佳。 |

| The synergistic reinforcement effect of potassium titanate whisker（PTW） and carbon nanotubes（CNTs） on fluororubber（FKM） was studied.The results showed that CNTs were easy to agglomerate in FKM matrix and had poor dispersion，while PTW had good dispersion in FKM matrix.When PTW/CNTs were used together，it showed synergistic effect，and the physical properties of the compound were improved significantly.At high temperature of 150 ℃，PTW/CNTs used together showed synergistic effect，and the physical properties of PTW/CNTs compound were better than that of the compound with one filler alone.The compression set of PTW/CNTs compound was larger than that of the compound with PTW alone，but slightly smaller than that of the compound with CNTs alone，indicating that the compression set resistance of PTW/CNTs compound was also slightly improved.The synergistic effect was the best when the PTW/CNTs ratio was 4/4，and the physical properties and compression set resistance of the compound were the best. |
