| 中文摘要: |
| 研究氧化石墨烯（GO）对绿色轮胎胎面胶用复合材料[GO/天然橡胶（NR）/溶聚丁苯橡胶（SSBR）复合材料]微观结构及动静态性能的影响。结果表明：添加适量GO有利于白炭黑在橡胶基体中的分散；随着GO用量的增大，GO/NR/SSBR复合材料的定伸应力、拉伸强度和撕裂强度逐渐增大，当GO用量为4份时GO/NR/SSBR复合材料的物理性能最佳，当GO用量为2份时GO/NR/SSBR复合材料的动态力学性能最佳。 |

| Abstract：The effect of graphene oxide（GO） on the microstructure and dynamic and static properties of
green tire tread compounds[GO/natural rubber（NR）/solution polymerized styrene butadiene rubber（SSBR）
composites] was studied. The results showed that the addition of an appropriate amount of GO was beneficial
to the dispersion of silica in the rubber matrix. As the amount of GO increased，the tensile stress，tensile
strength and tear strength of GO/NR/SSBR composites gradually increased. When the amount of GO was 4
phr，the physical properties of GO/NR/SSBR composites were the best，and when the amount of GO was 2
phr，the dynamic mechanical properties of GO/NR/SSBR composites were the best. |
