Abstract
We have observed and measured the optical anisotropy of graphene oxide (GO) in polyvinyl alcohol (PVA) using Stokes-Mueller Polarimetry (SMP). We found that it depends on the films with varying weight percent of GO in PVA. Analysis of polarized light transmitted through the ordered microstructure of GO in PVA reveals the anisotropic behavior due to its preferential alignment. The complex refractive index analysis of GO-PVA films complements the results of SMP.
