[Interface Science and Technology] Graphene Surfaces - Particles and Catalysts Volume 27 || Characterization

摘要： Graphene characterization is an important part of graphene research and contains measurements based on various microscopic and spectroscopic methods. Characterization includes layer number determination and the sample purity in terms of absence or presence of defects. Optical images of graphene samples in different solutions are the most effective method for the identification of the graphene production. This method is based on the color arising from the dispersibility of graphene and graphene oxide (GO).
