Description of PD IEC TS 62607-6-13:2020 2020

This part of IEC TS 62607 establishes a standardized method to determine the chemical key control characteristic

  • oxygen functional group content for powder consisting of graphene-based material like graphite oxide, graphene oxide, reduced graphene oxide and other types of functionalized graphene by

  • Boehm titration method.

In this document, the measured functional groups are carboxyl groups (also in the form of their cyclic anhydrides), lactone groups, hydroxyl groups and reactive carbonyl groups. Oxygen functional groups that exhibit no reactivity such as epoxides cannot be measured.

The oxygen functional group content is derived by the difference between NaHCO3, Na2CO3, NaOH and C2H5ONa consumption of dispersed graphene powders.

  • The oxygen functional group content determined according to this document is listed as key control characteristic in the blank detail specification for graphene IEC 62565-3-1.

  • The method is applicable for graphene powder and graphene related carbon 2D materials such as graphene oxide powder and reduced graphene oxide powder, which can be separated from the water and ethanol by centrifugation or filtration. This document is not applicable for sulfonate modified graphene.

  • In this document, the lower limits of detection (Annex C) for carboxyl groups, lactone groups, hydroxyl and carbonyl are 0,015 mmol/g, 0,037 mmol/g, 0,014 mmol/g, and 0,072 mmol/g, respectively.

  • This document targets graphene manufacturers and downstream users to guide their material design, production and quality control.
