We explore the property changes of polymer/graphite oxide (GO) nanocomposites as the degree of GO oxidation is changed. We have found that emulsifying a sample of GO separates the sheets into fractions of differing degrees of oxidation and we have demonstrated that this variation in degree of oxidation of GO plays a role in the improvement of tensile properties of GO based polymer nanocomposites. The interaction of GO sheets with the polymer matrix plays an important role in the mechanical properties of the nanocomposites. In addition, the mechanical properties are also dependent on the hydrophilic or hydrophobic nature of the polymers. We further investigate polymer nanocomposites made from oil-in-water emulsion systems stabilized by GO. The nature of the emulsion systems can be controlled by replacing a part of GO with graphene sheets as well as by altering the type of GO used. This approach provides a route to control the shape and conductivity of these polymer nanocomposites.<br/>
