The spatial orientation of the reinforcing elements in polymer-based composites plays a vital role controlling mechanical properties but there is no generally-accepted way quantifying at nanoscale plate-like fillers nanocomposites. A previous study found that intensity scattering Raman band dependent on axis laser polarization when beam parallel to surface graphene plane and demonstrated this could be used quantify graphene. Based approach, polarized spectroscopy here quantify, as an example, level oxide (GO) flakes different Furthermore, nanoplatelets quantitatively linked stress transfer reinforcement nanocomposites and, particular, method for determining Krenchel factor these directly from data demonstrated. This approach employed estimate effective Young's modulus graphene-based
