A method for quantitative determination of graphene materials in fibers by high temperature pyrolysis - element analysis is reported. This method takes advantage of the difference between the thermal stability of fiber and graphene itself to design the corresponding temperature gradient. Firstly, the fiber matrix is removed, and then the carbon element content ratio is measured by element analyzer. This method eliminates the influence of other impurities in the fiber. The experiment is reliable, simple to operate and the relative deviation conforms to the standard range, which is of great significance for quantitative analysis of the content of graphene materials in the fiber.
