| 中文摘要: |
| 以十八胺（ODA）对氧化石墨烯（GO）进行改性，采用乳液复合法制备ODA功能化GO（ODA-GO）/乳聚丁苯橡胶（ESBR）复合材料，并对其结构和性能进行研究。结果表明：ODA-GO在ESBR中的分散性良好，少量ODA-GO在ESBR中能够形成较强的填料网络；与ESBR胶料相比，ODA-GO/ESBR复合材料在0 ℃时的损耗因子（tanδ）增大，60 ℃时的tanδ减小；随着ODA-GO用量的增大，复合材料的物理性能和气密性能提高。 |
| 英文摘要: |
| The graphene oxide（GO） was modified by octadecylamine （ODA），the octadecylamine functionalized graphene oxide（ODA-GO）/emulsion styrene-butadiene rubber（ESBR） composite was prepared by emulsion composite method，and its structure and properties were studied. The results showed that，the dispersion of ODA-GO in ESBR was good，and strong filler network could be formed with small amount of ODA-GO. Compared with ESBR compound，the loss factor of ODA-GO/ESBR composite increased at 0 ℃ and decreased at 60 ℃. As the addition level of ODA-GO increased，the physical properties and airtight property of the composite were improved. |
