标准摘要
[中文适用范围]： 本部分IEC TS 62607建立了一种标准化方法，用于通过X射线光电子能谱（XPS）测定石墨烯基材料粉末的化学关键控制特性——元素组成和C/O比。元素组成（种类和相对丰度）由XPS光谱相应部分的元素结合能和积分峰面积得出。本文件适用于由石墨烯、双层石墨烯（2LG）、三层石墨烯（3LG）、少层石墨烯（FLG）、石墨烯纳米片（GNP）、还原氧化石墨烯（rGO）、氧化石墨烯（GO）和功能化石墨烯粉末组成的石墨烯粉末。典型应用领域包括微电子和热管理行业，如电池、集成电路、高频电子等。本文件可用于制造商的研究和开发以及下游用户的产品选择。 [外文原描述]： IEC TS 62607-6-21:2022 establishes a standardized method to determine the chemical key control characteristics - elemental composition, and - C/O ratio for powders of graphene-based materials by - X-ray photoelectron spectroscopy (XPS). The elemental composition (species and relative abundance) is derived by the elemental binding energy and integral peak area at corresponding portion of XPS spectrum. - The elemental composition refers to main elements in graphene powders, typically including carbon (C), oxygen (O), nitrogen (N), sulfur (S) , chloride (Cl) and silicon (Si). - This document is applicable to graphene powders consisting of graphene, bilayer graphene (2LG), trilayer graphene (3LG), few-layer graphene (FLG), graphene nanoplate (GNP), reduced graphene oxide (rGO), graphene oxide (GO), and functionalized graphene powders. - Typical application areas are the microelectronics and thermal management industries, e.g. batteries, integrated circuits, high-frequency electronics. This document can be used by manufacturers in research and development and by downstream users for product selection.
