摘　　要：柔性场发射阴极材料因其独特的可变形和弯曲特性,在电子织物、分布式传感器、纸上显示器以及建筑物表面的大型弯曲显示等领域,具有广泛的发展前景。利用纳米半导体组元构建兼具机械柔性和优越性能的功能柔性系统,是当前活跃的研究热点之一。本文概述了基于低维纳米结构的柔性场发射阴极材料的基本特点,阐述了以聚合物、石墨烯、碳纤维布等典型衬底材料制备场发射阴极材料的最新研究动态,论述了其在显示器和X射线管中的应用进展,对其今后的发展方向进行了展望。The flexible field emission cathode materials, with the unique advancements of deformability and bendability, have wide potential applications in the fields of electronic textiles, distributed sensors, paper displays and the large bending displays on building surface. Thus, the investigation on the flexible device systems, based on the semiconductor nanostructures with both high flexibility and excellent performance, becomes one of the hot research topics currently. In the present review, we firstly provide a brief introduction to the major features of the flexible field emission cathode materials. Then we make a comprehensive review on the research progresses focused on the fabrications of the flexible field emission cathode materials grown on the typical substrates of polymers, graphenes and carbon fabrics. Subsequently, we shed some lights on the potential applications of the flexible cathodes in the field emission displays and X-ray tubes. Finally, the future development directions of the flexible field emission cathode materials are prospected.
