本文分析了氧化石墨(GO)和还原氧化石墨烯(rGO)的各种制备方法。所获得的材料在它们的性质上不同,包括(除其他外)它们的氧含量。石墨、氧化石墨和还原氧化石墨烯的化学和结构性质先前使用拉曼光谱(RS)、X射线光电子能谱(XPS)和X射线衍射(XRD)进行了研究。在本文中,系统聚类分析(HCA)和方差分析(ANOVA)被用来跟踪所选参数的变化方向相对于这种氧化物的制备方法。我们发现,氧化方法影响最终产品的物理化学性质。该研究的目的是对所选特性进行统计分析,以便使用这些信息来设计具有与特定应用相关的特性的氧化石墨烯材料(即,在气体传感器中)。
In this paper, various graphite oxide (GO) and reduced graphene oxide (rGO) preparation methods are analyzed. The obtained materials differed in their properties, including (among others) their oxygen contents. The chemical and structural properties of graphite, graphite oxides, and reduced graphene oxides were previously investigated using Raman spectroscopy (RS), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). In this paper, hierarchical clustering analysis (HCA) and analysis of variance (ANOVA) were used to trace the directions of changes of the selected parameters relative to a preparation method of such oxides. We showed that the oxidation methods affected the physicochemical properties of the final products. The aim of the research was the statistical analysis of the selected properties in order to use this information to design graphene oxide materials with properties relevant for specific applications (i.e., in gas sensors).
