▎ 摘　　要

An approach for preparing highly conductive poly(methyl methacrylate)-reduced graphene oxide (PMMA/rGO) composites by in situ polymerization of methyl methacrylate (MMA) monomer in the presence of iron metal induced deoxygenated rGO is reported. The obtained PMMA/rGO exhibited excellent electrical properties with a percolation threshold as low as 0.1 wt.% and electrical conductivity of 14 S/m at only 0.8 wt.% rGO loading. Moreover, with only 0.4 wt.% rGO content, the glass transition temperature (T-g) of the prepared PMMA/rGO composite was enhanced by 16 degrees C which corresponds to 17% improvement when compared to that of the neat PMMA. Furthermore, tensile strength increased by 26% as compared to that of the neat PMMA.
