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.
