Description
Summary:PMMA-HRG (Poly (methyl methacrylate)-highly reduced graphene) nanocomposites were prepared by a solution blending method, and the effect of HRG loading on the electrical, mechanical, and thermal properties of the materials was studied. PMMA-HRG nanocomposites achieved a percolation threshold of 0.37 vol.% (0.039 S/m) and a maximum electrical conductivity as high as 85 S/m at a loading of 2.7 vol. %. The homogeneous dispersion of HRG sheets overcame aggregation in solution and gave a uniformly distributed single layer graphene in the PMMA matrix. The T g of PMMA-HRG increased by 19°C with a loading of 0.27 vol. %, and the storage modulus of the nanocomposites increased by 37% in the glassy region with a loading of 2.7 vol. %.
