纳米制造 关键控制特性 石墨烯基材料 官能团：TGA-FTIR

[中文适用范围]： 本部分IEC TS 62607建立了一种标准化方法，用于通过热重分析（TGA）结合傅里叶变换红外光谱（FTIR）（称为TGA-FTIR）来确定功能化石墨烯基材料和氧化石墨烯的化学关键控制特性-功能基团。功能基团的含量是通过TGA中样品质量随温度的变化来推导的。在这些质量变化过程中产生的材料随后通过耦合FTIR进行分析，以识别功能基团。 根据本文件确定的功能基团将作为关键控制特性列在石墨烯粉末的空白详细规范IEC 62565-3-1中。 该方法适用于在TGA过程中可以通过高温热解和气化的功能化石墨烯粉末和氧化石墨烯。 典型的应用领域包括石墨烯制造商的质量控制和下游用户的产品选择。 [外文原描述]： IEC TS 62607-6-18:2022(E) establishes a standardized method to determine the chemical key control characteristic functional groups for functionalized graphene-based material and graphene oxide by thermogravimetry analysis (TGA) coupled with Fourier transform infrared spectroscopy (FTIR), referred to as TGA-FTIR. The content of functional groups is derived by changes in mass of the sample as a function of temperature using TGA. Materials evolved during these mass changes are then analysed using coupled FTIR to identify functional groups. The functional groups determined according to this document will be listed as a key control characteristic in the blank detail specification for graphene IEC 62565-3-1 for graphene powder. The method is applicable for functionalized graphene powder and graphene oxide that can be pyrolysed and gasified with elevated temperature during TGA. Typical application areas are quality control for graphene manufacturers, and product selection for downstream users.
