中文摘要: 单壁碳纳米管(SWNTs)和石墨烯(graphene)分别是一维和二维碳纳米材料,它们都具有高导电率和热导率、高载流子迁移率、高强度和刚度等特性,在能源、电子尤其是能量的储存和转化方面具有很好的应用前景。但它们也存在诸如易聚集、成膜后导电性和机械性能降低等问题。由于二者在结构和性质上具有互补性,形成杂化材料不仅能弥补各自的不足、保持它们原来的优异性能,而且杂化材料的性能优于单独一种材料。本项目拟使用电弧法一步合成SWNTs/graphene杂化材料及其平行取向膜,探索电弧炉中SWNTs和graphene共同生成的机理,并检测该材料作为有机光伏电池透明电极的性能。在此基础上,电弧法一步合成SWNTs/Graphene/MOx三元杂化材料,并作为电极材料应用于超级电容器的研制。

英文摘要: Single-walled carbon nanotubes (SWCNTs) and graphene are one- and two dimensional carbon nanomaterials, respectively. They all have high electrical conductivity, high thermal conductivity, high carrier mobility, and ultrahigh mechanical strength. They show potential applications in energy and electronics, especially in energy transformation and storage. However, CNTs and graphene have their own drawbacks, such as easy to aggregate, weak dispersibility, and their films showing lower conductivity and degraded mechanical properties. As SWCNTs and graphene are mutually complementary in structure and properties, when they are integrated into a hybride, the hybrid not only preserve their intrinsic electrical and mechanical properties and make up for the drawbacks, but also show better properties than one of them. In this project, we will synthesis SWCNTs/graphene hybrid and its aligned films in one step by arc discharge method, exploring the intergrowth mechanism of SWCNTs and graphene, and determine the performance of the hybride as the transparent electrode of organic photovoltaic cell. Furthermore, SWNTs/graphene/metal oxide three component hybrid will be synthesized in one step by arcing, and the performance of the hybrid as the active electrode materials of supercapacitors will be investigated.
