| 中文摘要: |
| 采用硅烷偶联剂KH570功能化氧化石墨烯（GO），再通过原位自由基聚合法在GO表面接枝聚氨酯（PU），得到GO接枝PU（GO-g-PU）复合纳米片，以其对乙烯-醋酸乙烯无规共聚物（EVA）进行改性。结果表明：GO-g-PU复合纳米片能均匀分散在EVA基体中，GO-g-PU/EVA纳米复合材料的物理性能与热稳定性能均优于EVA和GO/EVA复合材料。 |
| 英文摘要: |
| Polyurethane（PU） was grafted onto the surfaces of graphene oxide（GO） which was functionalized by a silane coupling agent KH570 via in-situ radical polymerization，the synthesized products GO-g-PU composited nanosheets were used to modify ethylene vinyl acetate（EVA）.The results showed that GO-g-PU composited nanosheets could uniformly disperse in the EVA matrix，the physical properties and thermal stability of GO-g-PU/EVA composites were superior to those of EVA and GO/EVA composites. |
