Preparation and Characterization of 3-Glycidoxypropyltrimethoxysilane Functionalized Graphene Oxide

Abstract:

The graphene oxide (GO) was prepared by the Hummers method, and then functionalized by 3-glycidoxypropyltrimethoxysilane. Functionalized graphene oxide (FGO) was characterized by using Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis (TG). The results show that 3-glycidoxypropyltrimethoxysilane reacted with hydroxyl group of graphene oxide. The FGO have a sheet-like structure with wrinkles. The shifts of XRD peaks to low degree for FGO indicate the occurrence of intercalation of 3-glycidoxypropyltrimethoxysilane and as well as increase in the thermal stability.
