| Abstract: |
| 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. |
