IEC TS 62607-6-13:2020

IEC TS 62607-6-13:2020 establishes a standardized method to determine the chemical key control characteristic
• oxygen functional group content
on 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.
