By in situ emulsion method to prepare polymethyl metaacrylate (PMMA) and graphene nanocomposite materials showed remarkable properties: the in glass transition temperature was increased from 5-80 0C, the decomposition temperature was 50 0C higher, the stiffness is 46 % higher compared to the pure PMMA. The reduction of exfoliated graphene oxide in TGO-PMMA nanocomposite after synthesis by hydrazine is more effective than the reduction of graphene oxide into graphene and then synthesizing the nanocomposite with PMMA. There are some differences in the structure and morphology of two nanocomposite samples (SEM and TEM) synthesized by these two methods, leading differences in their properties, as well as the original pure PMMA. These results open up new potential for the application of graphene and resulted nanocomposites.
