The impacts of Graphene Oxide (GO) as a nanocomposite ingredient on polymer morphology and resultant property alterations, including mechanical, barrier, and electrical conductivity, are briefly reviewed in this work. This review primarily focuses on the effects of stress measurements on mechanical enhancement. The mechanical characteristics of nanocomposite materials are primarily influenced by the variable degrees of GO aggregation in various polymer matrices as a result of their weak inter-particle attractive interactions. By examining the surface morphology of these nanocomposites with scanning probe microscopy, such as Atomic Force Microscopy (AFM) and scanning electron microscopy, it is possible to evaluate the near-surface dispersion of GO in polymer/GO nanocomposites (SEM) Wide-Angle X-Ray Scattering (WAXD) can be used to study GO dispersion in the bulk by examining the diffraction peaks associated with the undispersed GO fraction in the polymer matrix. We examine how the hydrophilicity of graphene oxide and its hydrogen bonding potential can improve the water flux of these nanocomposite materials in mem- brane applications. The percolative dispersion of GO nanoparticles can also advantageously increase the electrical conductivity of polymer films and bulk polymers, although this often necessitates further chemical processing of the GO nanoparticles to convert them to reduced GO.
