Fast and Cost-Effective Synthesis of High-Quality Graphene on Copper Foils Using High-Current Arc Evaporation

Abstract

In this paper, we present an innovative and ultra-fast process for the deposition of high-quality graphene on different metal foils and thin metal films. The graphene layer can be homogeneously deposited in only 30 s process time. Due to the weak adhesion to the substrate material, the monolayer graphene is easy to transfer using the established processes. For the production, we use magnetic filtered high-current arc evaporation (Φ-HCA) with a solid, graphitic carbon source. This ultra-fast growth process can pave the way towards a cost-effective graphene synthesis for the mass production e.g., in a roll-to-roll process, avoiding time consuming established processes.

A review of graphene synthesis by indirect and direct deposition methods

“…Another direct method for synthesizing graphene is by the rapid evaporation of bulk carbon onto heated Ni foils in a vacuum evaporator using spectroscopically pure graphite rods as electrodes [111]. Single-layer graphene sheets can be fabricated by an ultrafast growth process, referred to as magnetic-filtered, high-current arc evaporation, which uses a graphite carbon source, a Cu substrate preheated in H 2 , and cooling in Ar/H 2 atmosphere [112]. Multilayer graphene films can be grown on Cu and Ni substrates at a moderate temperature by energetic PVD [113].…”

The simulation of terahertz waves transmission in the arc plasma

“…There is increasing attention to arc discharge due to its wide range of applications, including arc welding [1,2], spray coating [3,4], materials processing [5], arc lamp [6], and some emerging applications: synthesis of graphene [7,8] and other Nano-Materials [9]. In order to make better use of arc discharge to develop new applications, it is important to learn the plasma properties, especially the electron density and temperature [10,11].…”

In Vitro Lung Models to Assess the Mechanistic Genotoxicity of Characterised Few-Layer Graphene

“…Largely, graphene is in competition for this technology with indium tin oxide (ITO) which expresses marginally better properties than graphene. Graphene production is increasing in quality and thus physical properties, this ultimately means graphene could replace ITO as a surface coating (Lux et al, 2018). With advantageous and superior flexibility and durability, graphene encompasses the role of modern nanotechnology in favour of conventional flexible electronics (Li et al, 2018a).…”
