摘要
利用埃洛石(HNTs)内部空间负载甲基丙烯酸甲酯(MMA),通过γ甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)修饰氧化石墨烯(GO),随后利用二者构建了具有半有机半无机结构的杂化三维网络.通过扫描电子显微镜(SEM)、红外光谱(FT IR)、拉曼光谱、X射线光电子能谱(XPS)等手段对样品进行表征.结果表明,成功制备了半有机半无机杂化三维网络气凝胶材料,材料具有纳米级孔隙,其热稳定性也保持在较高水平,为后续该材料在光电功能领域的应用奠定了结构基础.

Abstract:
In this paper,a hybrid three-dimensional network with a semi-organic semi-inorganic structure was constructed by loading.Methyl methacrylate(MMA) in the inner space of halloysite nanotubes(HNTs) and modifing graphene oxide(GO) with γ-methacryloxypropyltrimethoxysilane(KH570).The sample was characterized by scanning electron microscopy(SEM),infrared spectroscopy(FT-IR),Raman spectroscopy,and X-ray photoelectron spectroscopy(XPS).The results show that the hybrid three-dimensional network aerogel material has been successfully prepared.The material has nano-scale pores and its thermal stability is also maintained at a high level,which lays a structural foundation for the subsequent application of the material in the field of photoelectric function.
