中文摘要： 透明导电薄膜无论是在学术界还是产业界都受到长期广泛的关注。碳纳米管，银纳米线和石墨烯分别作为三个最具有潜力的材料逐步推进了这个领域的发展。但是性能上的差距和规模化制备，价格的因素都使其不可能彻底替代现有的氧化铟锡。本项目采用静电纺丝和溶液还原两种自下而上的制备方法，使用廉价的，可规模化的，接触电阻极小的铜纳米线导电网络作为基础，通过与二维碳纳米材料石墨烯的复合，有效提高薄膜的导电性，并且可以形成均匀、连续的导电电极，对铜纳米线的抗氧化性和长期稳定性都有所帮助。通过优化实验条件，制备出透光率与导电性兼顾的柔性铜纳米线/石墨烯复合透明导电薄膜，研究复合薄膜两种不同纳米材料之间的接触电阻，导电机理以及光学、电学性质，为其在有机发光二极管和太阳能电池中透明电极的应用打下良好的实验基础。

英文摘要： The transparent conductive films have attracted much attention in recent years both in industrial and academic fields. The most promising materials among these are carbon nanotube, graphene, and silver nanowires. But three issues still remain, poor performance, high price and small-scale production. In this project, two main methods, electrospinning and hydrothermal reduction, are applied to synthesize cheap and scalable copper nanowires. The two-dimensional nanomaterial, graphene, is then coated on the copper nanowires films to enhance electrical conductivity, continuity, homogeneity, oxidation resistance and long-term durability. To optimize experimental parameters, we aim to produce copper/graphene hybrid transparent conductive films with a remarkable combination of high electrical conductivity and optical transparency, flexibility and stability. The contact and electric path between two nanomaterials, conducting mechanism and optical/electrical properties will also be investigated in this project. This work will provide bases for application of transparent conductive electrodes in organic light emitting diode and solar cell areas.
