Influence of graphite precursor on composition, morphology and structure of graphene materials obtained by thermal exfoliation-reduction of graphite oxide

This study aimed to determine the influence of the graphite precursor on the composition, morphology and structure of graphene materials obtained by thermal exfoliation-reduction of graphite oxide. The influence of the graphite precursor structure on the properties of the obtained graphene material is little understood in light of available literature data. Relating the composition, morphology and structure of graphene materials to the properties of the graphite precursor used is an important cognitive problem that needs to be solved. Moreover, the task set in the present research was to develop an oxidation method that would be more efficient compared to previously used modifications of the Hummers method. The descriptive table consists of results data from: * Elemental analysis * Analysis of graphite mineral matter * X-ray structural testing (XRD) * Raman spectroscopy * Thermogravimetric (TG) analysis * Structural infrared studies (FT-IR) * Scanning electron microscopy (SEM) * X-ray photoelectron spectroscopy (XPS) * Atomic force microscopy (AFM) * Porous texture analysis by N2 sorption at 77K

本研究旨在探究石墨前驱体对氧化石墨经热剥离-还原法制备的石墨烯材料的组成、形貌与结构的影响。就现有文献资料而言，石墨前驱体结构对所制石墨烯材料性能的影响尚未得到充分阐明。将石墨烯材料的组成、形貌与结构与其所使用的石墨前驱体的性质相关联，是亟待解决的重要科学认知问题。此外，本研究的另一目标是开发一种相较于此前所采用的哈默斯（Hummers）法改进方案更为高效的氧化制备方法。本描述性表格涵盖以下测试所得的结果数据：* 元素分析 * 石墨矿物质分析 * X射线结构测试（XRD） * 拉曼光谱分析 * 热重（TG）分析 * 结构红外光谱研究（FT-IR） * 扫描电子显微镜（SEM）观测 * X射线光电子能谱（XPS）分析 * 原子力显微镜（AFM）观测 * 77K下氮气吸附法多孔结构表征
