The characterization of the morphology of the samples containing a homogenous mixtures of epoxy and graphene nanoplatelets (GNPs) produced by solution compounding and shear mixing techniques were carried out in this study. The research work is aimed at evaluation of the morphology in terms of crystallinity of the polymer nanocomposites using wide angle X-ray diffraction (WAXRD) and Scanning Electron Microscopy (SEM) in accordance with ASTM D3417. The nanoparticles were varied in 10, 20 and 30 % by weight fraction of the PNCs. Highly crystalline peaks at 2θ values of 20.3O, 24.46O and 23.80O for 10, 20 and 30 % GNP weight fractions respectively, were observed. These show significant improvements in the morphology of polymer nanocomposites with varying loading of graphene nanoplatelets. The nanocomposites have a characteristics microstructure dimensions comparable to critical length scale of physical phenomena that gives to the unique mechanical properties. The use of solution compounding coupled with high shear mixing as dispersion technique influences the morphology of the polymer nanocomposites positively, thus its suitability for light weight and high strength industrial applications in the automobile, electronics and aerospace industries.
