首次提出了一种制备水溶性磷酸化石墨烯的有效方法。采用改进的Hummers法合成了氧化石墨烯（GO），并以四氢呋喃（THF）为溶剂，用磷酰氯和三乙胺对GO进行了磷酸酯化修饰。采用X射线衍射、傅里叶变换红外光谱、扫描电子显微镜、分析X射线光谱、原子力显微镜、漫反射光谱、热重分析、差热重分析、Brunauer-Emmett-Teller和Barrett-Joyner-Halenda方法、拉曼光谱、和X射线光电子能谱。用返滴定法测定了PGO和PGO-400的酸度。PGO-400具有卓越的电子和热性能、阳离子交换能力和水稳定性。阳离子交换容量的组合。
An efficient method for the preparation of water-soluble phosphated graphene for the first time is developed. Graphene oxide (GO) was synthesized through a modified Hummers’ method and functionalized by phosphate groups with phosphorus trichloride and triethylamine in tetrahydrofuran (THF). The morphology and chemical structure of phosphorylated graphene oxide (PGO) and heat-treated PGO (PGO-400) were characterized by X-ray diffraction, Fourier transform infrared spectrometry, scanning electron microscopy, analytical X-ray spectroscopy, atomic force microscopy, diffuse-reflectance spectrometry, thermogravimetric analyses, differential thermogravimetric analysis, Brunauer–Emmett–Teller and Barrett–Joyner–Halenda methods, Raman spectroscopy, and X-ray photoelectron spectroscopy. The acidity of PGO and PGO-400 was measured by a back-titration method. PGO-400 offers extraordinary electronic and thermal properties, cation-exchange capacity, and water dispersibility. The combination of cation-exchange capacity ...
