Anotácia textu normy IEC/TS 62607-6-18-ed.1.0 :

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.
