Abstract: Graphene being a highly conductive material that consists of two dimensional sheets of sp2-hybridized carbon atoms in honeycomb symmetry have attracted the attention of material scientists in various fields since its discovery in 2004 by Novoselov et al1, due to their outstanding mechanical, thermal and electricalproperties.2 Excellent properties and inexpensive sources (graphite) have spurred intensive interest in developing cost effective high performance polymer nanocomposites. The present study deals with the preparation and characterization of poly(methyl methacrylate) [PMMA]�reduced graphene oxide (RGO) nanocomposites. The effect of incorporation of varying amounts [i.e. ranging from 0.1-2.0 % w/w] of reduced graphene oxide (RGO) on the electrical and morphological properties of PMMA was investigated. The obtained nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR) , scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The composite exhibited conductivities in the 10-9-10-3 S/cm range, depending on the amounts of RGO and PMMA.Keywords: RGO (reduced graphene oxide), PMMA, electrical conductivity.                   :  FTIR spectra of (a) GO (b) RGO (c) PMMA/RGO compositeReferences: [1] Novoselov, K.
