SiO2@Graphene Composite Materials Obtained through Different Methods Used as Substrate Materials

In this work, two different methods were applied to prepare SiO2-Graphene composite materials (SiO2-G). One way to synthesize composite materials was stirred carboxyl functionalized graphene and tetraethyl ortho silicate (TEOS) together at low temperature. In other way, SiO2-G were obtained via an one-pot hydrothermal reaction. We employed SEM to characterize the direct structure and morphology information of materials, subsequently. It could be clearly observed that their morphology were greatly affected by the different preparation methods and resulted in a tremendous change occurred. It is no question that the as-prepared materials with different structure can be used as different substrate materials.
