Abstract

Field emission (FE) applications, essential in cutting-edge technologies like microwave devices and particle accelerators, increasingly utilize carbon nanomaterials like graphene and carbon nanotubes. However, their production encompasses complex challenges, and structural intricacies affect their efficacy. In this research, we advanced the development of graphene fibers using a wet-spinning method, marking a progression in FE applications. The process entailed control of fiber coagulation and draw ratios to optimize their internal structure. Furthermore, we introduced a continuous reduction technique to increasing the electrical conductivity of the graphene fibers. The produced fibers showed threshold electric fields of 1.1, 1.0, 0.8 and 0.6 V/㎛, maximum currents density of 1.09, 1.19, 1.22 and 1.25 A/cm2. Field enhancement factor (β) 9900, 10216, 12007 and 20830 showed marked improvement correlating with increased draw ratios, highlighting their field emission properties. This study illuminates the potential of graphene fibers as FE materials, paving the way for future advancements in this domain.
