Graphene oxide/polymethylmethacrylate (GO/PMMA) and surface-functionalized graphene/ PMMA composites were prepared by solution blending. The morphologies of these composites were visualized by TEM, SEM, and AFM. By incorporating GO or surface-functionalized graphene into PMMA, both tensile strength and elongation at the break of the composites were enhanced, and the surface-functionalized graphene has the better effect on the composite than GO.

Key words: graphene, polymethylmethacrylate, composite, mechanical property
