One of the innovative methods to improve the overall function and performance of polymeric materials is through the development of nanocomposite materials.  Purposely doped nanocomposite materials allow for scientists and engineers to produce and tailor the material properties suitable for specific needs and objectives.  For this research project, we seek materials exhibiting properties that are chemically inert, durable, flexible, cheap, and highly piezoelectric with longevity.  A polymeric system chosen to exhibit these properties is Polyvinylidene Fluoride (PVDF) doped with neutral and reduced Graphene Oxides (GOs).  In this work, we will present the optimization of the piezoelectric properties of the PVDF films through GOs doping which has been shown to promote β-phase formation.  The different experimental approaches used to fabricate the GO + PVDF composites have been conducted and the electrospray technique shows the unique advantages over others.  The experiment leverages the high electric field which seems to promote higher uniformity and controlled orientation of the piezoelectricity in the PVDF nanocomposites.  We will also present and discuss how the sample preparation and fabrication parameters affect the material properties such as, applied voltage, GO doping concentration in PVDF. Further, we will discuss our Raman, XRD, FTIR, and SEM results associated with our findings.<br/>
