| 摘要: |
| 为了提高超高分子量聚乙烯的热性能，本文通过溶液共混的方法利用氧化石墨烯改性不同分子量的超高分子量聚乙烯，然后利用红外测试(FTIR)、X射线衍射测试(XRD)、扫描电镜测试(SEM)、差热扫描量热分析仪(DSC)和热失重分析(TG)的方法对超高分子量聚乙烯/石墨烯纳米复合材料的结构、表面形态和性能进行了研究.通过分析测试表明氧化石墨烯在超高分子量聚乙烯/石墨烯纳米复合材料中的分散性良好，氧化石墨烯的添加量为0.3%时，石墨烯/超高分子量聚乙烯的复合材料的热稳定性等性能最好, 与原材料相比提高了3 ℃.

| Abstract: |
| In order to improve the thermal stability of UHMWPE, UHMWPE of different molecular weights were modified with GNS prepared by solution blend method, X-ray diffraction(XRD), scanning electron microscope (SEM), differential thermal scanning calorimetry (DSC) and thermogravimetric (TG) were used to characterized the structure, surface morphology and property of the ultra-high molecular weight polyethylene(UHMWPE)/GNS nanocomposite.The result shows that GNS are well distributed into nanocomposite, when an amount of 0.3% GNS(weight percent) was used, the thermal stability and performance of nanocomposite is best of all, and it wsa increased 3 ℃ compared with the raw material.
