摘要：
光学微纤维在工业的各个领域中找到了新的应用，这反过来又要求其具备耐磨性、环境友好性和易用性。然而，光学微纤维是易碎的。在此，我们报告一种通过用绿色提取的石墨烯覆盖层修饰其表面来延长微纤维寿命的新方法。石墨烯薄膜是通过在水性介质中分散 shungite 矿物样品获得的。为此，我们将光纤拉锥，并用与金纳米颗粒混合的石墨烯薄膜对其进行雕刻修饰。我们观察到，由于表面修饰，微纤维的寿命和存活率与裸微纤维相比提高了 5 倍。嵌入的金纳米颗粒还可用于增强灵敏度和其他应用。
英文摘要：
Optical microfibers finds new applications in various fields of industry, which in turn requires wear resistance, environmental friendliness and ease of use. However, optical microfibers are fragile. Here we report a new method to prolong the microfiber lifetime by modifying its surface with green-extracted graphene overlayers. Graphene films were obtained by dispergation of shungite mineral samples in an aqueous medium. For this, we tapered optical fibers and sculptured them with graphene films mixed with gold nanoparticles. We observed that due to the surface modification the lifetime and survivability of the microfiber increased 5 times, as compared to the bare microfiber. The embedded gold nanoparticles can also be utilized for enhanced sensitivity and other applications.
