| 中文摘要: |
| 氧化石墨烯（GO）先用促进剂CZ改性，再用水合肼还原制备水合肼和促进剂CZ共改性GO（H-C-GO），研究绿色轮胎用功能化石墨烯/天然橡胶（NR）复合材料的性能。结果表明：水合肼和促进剂CZ共改性的H-C-GO的团聚显著减少且与橡胶之间的相容性较好；H-C-GO/NR复合材料具有比GO/NR复合材料或水合肼还原GO/NR复合材料更高的拉伸强度、更好的抗湿滑性能和更低的滚动阻力。 |
| 英文摘要: |
| Graphene oxide（GO） was first modified with accelerator CZ，then reduced with hydrazine hydrate to prepare hydrazine hydrate and accelerator CZ co-modified GO（H-C-GO），and the properties of functional graphene/natural rubber（NR） composites for green tire were studied.The results showed that，H-C-GO co-modified by hydrazine hydrate and accelerator CZ could significantly reduce the agglomeration and improve the compatibility with rubber，H-C-GO/NR composite had higher tensile strength，better wet skid resistance and lower rolling resistance than GO/NR composite and hydrazine hydrate reduced GO/NR composite. |
