摘要

我们使用斯托克斯-穆勒极坐标法（SMP）观察并测量了聚乙烯醇（PVA）中氧化石墨烯（GO）的光学各向异性。我们发现，这取决于 PVA 中不同重量百分比的 GO 薄膜。对透过 PVA 中 GO 有序微结构的偏振光进行分析，可以发现由于其优先排列而产生的各向异性行为。GO-PVA 薄膜的复折射率分析补充了 SMP 的结果。

Studies of anisotropic polarization in graphene oxide doped in PVA

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.
