英文摘要： Due to its unique two-dimensional structure and exceptional physical and chemical properties, graphene is widely considered to be an ideal material for fabricating high-performance transparent conductive films, and thus expected to replace resource-scarce and brittle indium tin oxide and show great potential in many fields such as flexible display devices, organic solar cells, and smart windows. This project will target potential utilization of nanoscale assembly techniques in transparent conductive films, propose to assemble a kind of structure-tunable periphery-functionalized graphene sheets with silver nanorods at the molecular level or nanoscale, process them into silver nanorod-bridged graphene-based transparent conductive films, and study the opto-electrical properties of the thus-fabricated films. The project will elaborately tailor the structure of periphery-functionalized graphene with silver nanorods, systematically investigate the effects of the interface number of graphene sheets and the interface type between graphene sheets within these films on their opto-electrical properties, and establish the structure-property relationships of these transparent conductive films. Based on optimizations on components and structures of silver nanorod-bridged graphene-based transparent conductive films, the projec
