Among different inorganic and organic polarizer elements, thin-film light polarizers occupy a special place because of their flexibility, ease of integration into any optoelectronic circuit, and good functioning in the visible and near-infrared spectral range and can compete with Glan and Nicolas volumetric prisms. This paper presents the results of a study on how carbon-based nanoparticles influence on the basic properties of a well-known PVA-based polymer matrix, using which it is possible to obtain good transparency for parallel light components. An accent is made on graphene oxide nanoparticles, which are used as PVA sensitizers. It was shown for the first time that the structuring of PVA with graphene oxides allows an increased transmittance of the parallel light component to be obtained, saving the transmittance of the orthogonal one. Moreover, the graphene network can increase the mechanical strength of such thin-film PVA-based polarizers and provoke a change in the wetting angle. These advantages make it possible to use graphene oxide-structured thin-film light polarizers based on a PVA matrix as an independent optoelectronic element. Some comparative results for polarizers based on PVA-C structures are shown as well.
在不同的无机和有机偏振器元件中，薄膜光偏振器占据着特殊的地位，因为它们具有柔韧性、易于集成到任何光电子电路中，并且在可见光和近红外光谱范围内功能良好，能够与格兰和尼科尔斯体视棱镜相媲美。本文介绍了一项关于碳基纳米颗粒如何影响一种著名的基于聚乙烯醇（PVA）的聚合物基体基本性能的研究结果，利用该基体可以获得平行光分量的良好透明度。重点研究了用作PVA敏化剂的氧化石墨烯纳米颗粒。首次表明，用氧化石墨烯对PVA进行结构化处理能够提高平行光分量的透过率，同时保持正交光分量的透过率。此外，石墨烯网络可以提高这种基于PVA薄膜的偏振器的机械强度，并引起润湿角的变化。这些优点使得基于PVA基体的氧化石墨烯结构的薄膜光偏振器能够作为一种独立的光电子元件使用。文中还给出了基于PVA-C结构的偏振器的一些对比结果。
