由于器件小型化的迅猛发展，人们对所谓的纳米电子器件产生了极大的兴趣。微纳米电阻和电容的制备已经取得了一定的进展，但到目前为止，在纳米线圈电感方面的研究还很少。这是因为具有围绕金属芯盘绕的线的螺线管的设计的小型化的物理限制。因此，虽然晶体管变得越来越小，但电子产品中的基本电感器仍然相对庞大。几乎没有方法可以制造导电聚合物线圈和石墨烯基动力学纳米电感器，但它们的大规模制造过程很复杂，大多超出了目前可用的商业技术。因此，需要一种更简单、可扩展且鲁棒的制造技术来克服这一瓶颈。在这项工作中，我们展示了一种新的技术，包括使用激光雕刻机的（聚）乙烯醇（PVA）/氧化石墨烯膜复合材料，导致在一个大的感应效应的激光光刻。我们将这种行为归因于由通过π-π相互作用连接到还原氧化石墨烯薄片的聚乙炔链组成的高曲率扭曲螺旋位错型导电通路的形成，从而导致诱导效应。
There is great interest in so-called nano-electronic devices due to the furious rate of device miniaturization. Fabrication of micro and nano scale resistors and capacitors have already been achieved steadily, but so far, there has been little development in the way of nano-scale coil inductors. This is because of the physical limitations in miniaturization of the design of a solenoid with wires coiled around a metallic core. So, while transistors get steadily smaller, basic inductors in electronics remained relatively bulky. Few methods exist for creating conductive polymer coils and graphene-based kinetic nano-inductors, but their large-scale fabrication process is complex and mostly beyond the current commercial technology available. So, a simpler, scalable, and robust fabrication technique is needed to overcome this bottleneck. In this work we demonstrate a new technique consisting of the laser lithography using a laser engraver of a (poly)vinyl alcohol (PVA)/graphene oxide film composite which results in a large inductive effect. We attribute this behavior to the formation of high curvature twisted screw dislocation type conductive pathways composed of polyacetylene chains linked by pi-pi interactions to reduced graphene oxide flakes resulting in inductive effect.
