Abstract

Graphene oxide was functionalized with simultaneous reduction to produce phosphonated reduced graphene oxide in a novel, fully scalable, one-pot method. The phosphonic derivative of graphene was obtained through the reaction of graphene oxide with phosphorus trichloride in water. The newly synthesized reduced graphene oxide derivative was fully characterized by using spectroscopic methods along with thermal analysis. The morphology of the samples was examined by electron microscopy. The electrical studies revealed that the functionalized graphene derivative behaves in a way similar to chemically or thermally reduced graphene oxide, with an activation energy of 0.014 eV.

摘要

通过同时还原对氧化石墨烯进行功能化处理，采用一种新颖、完全可扩展的一锅法制备了膦酸化还原氧化石墨烯。氧化石墨烯与三氯化磷在水中反应，得到了石墨烯的膦酸衍生物。通过光谱方法和热分析对新合成的还原氧化石墨烯衍生物进行了全面表征。通过电子显微镜检查了样品的形态。电学研究表明，功能化石墨烯衍生物的行为方式类似于化学还原或热还原的氧化石墨烯，其活化能为0.014电子伏特。
