Popis: A method for the identification of graphene materials in fibers by high-resolution transmission electron microscopy (HRTEM)-Energy Dispersive Spectroscopy (EDS) has been reported. Two ways to prepare samples are available, namely the dissolution extraction and the ultra-thin sectioning method. For samples prepared by any method, the graphene material in the fiber can be detected by the following steps. Firstly,the elemental composition of the microparticle is demonstrated by EDS. Secondly, the morphology of the particles in the fiber can be obtained by TEM, and the number of layers of graphene materials is able to observed directly from the edge of sheet.
