摘要: 采用硅烷偶联剂γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)对氧化石墨烯(GO)进行有机改性,得到了改性氧化石墨烯(GO-KH570),然后在GO-KH570表面接枝苯乙烯(St),制备了一种表面接枝聚苯乙烯(PS)的阻燃剂(GO-KH570)-g-PS。采用傅里叶变换红外光谱仪、X射线光电子能谱、热失重分析仪和扫描电子显微镜对GO、GO-KH570和(GO-KH570)-g-PS进行了测试表征。结果表明,成功合成了接枝率为20.37 %的(GO-KH570)-g-PS。

Abstract: In this work, graphene oxide(GO) was surface modified by silane coupling agent γ-methacryloxy propyl trimethoxyl silane, and then styrene was grafted onto the surface of the surfacemodified GO for the purpose of flame retardancy. The resultant (GO-KH570)-g-polystyrene (PS) was characterized by Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis and scanning electron microscopy.The results indicated that (GO-KH570)-g-PS was successfully prepared.
