| 中文摘要: |
| 采用改进Hummers法制备氧化石墨烯（GO），并以聚乙烯亚胺为“桥接分子”制备GO/羧基丁腈橡胶（XNBR）
纳米复合材料，考察GO/XNBR纳米复合材料的微观形貌、力学性能和耐有机溶剂渗透性能。结果表明：GO与XNBR基
体结合良好且分散均匀；GO/XNBR纳米复合材料的拉伸强度由纯XNBR胶料的3. 9 MPa提高到7. 2 MPa（GO用量为0. 7
份），提高了约1. 8倍；随着GO用量增大，GO/XNBR纳米复合材料对有机溶剂的耐渗透时间明显延长。 |
| 英文摘要: |
| Graphene oxide（GO） was prepared by modified Hummers method，and GO/carboxylated
nitrile rubber（XNBR） nanocomposites were prepared with polyethyleneimine as “bridging molecule”.
The micro morphology，mechanical properties and organic solvents impermeability of the GO/XNBR
nanocomposites were investigated. The results showed that GO and XNBR matrix were bonded well and GO
was uniformly dispersed. The tensile strength of the GO/XNBR nanocomposites increased from 3. 9 MPa
of pure XNBR compound to 7. 2 MPa（GO dosage was 0. 7 phr），which was about 1. 8 times increase. With
the increase of GO dosage，and the organic solvents impermeability time of GO/XNBR nanocomposites was
obviously prolonged. |
