GB/T 38114-2019 Nanotechnologies—Quantitative analysis of the surface oxygen functional groups on graphene materials—Chemical titration method

Scope

This standard specifies the method outline, reagents, instruments, measurement steps, result calculation and presentation, and test reports for quantitatively analyzing the content of oxygen-containing functional groups on the surface of graphene powder materials by chemical titration.
This standard is applicable to the determination of graphene powder materials. The detection limits of carboxyl groups, lactone groups, phenolic hydroxyl groups, and carbonyl groups on the surface of graphene materials are 0.015 mmol/g, 0.037 mmol/g, 0.014 mmol/g, and 0.072 mmol/g, respectively.
This standard is not applicable to sulfonated graphene materials. For the quantitative analysis of the content of oxygen-containing functional groups on the surface of other carbon materials, this standard can be referenced.
