This work proposed a novel nanomanufacturing approach, in which a submerged arc discharge method was adopted to produce graphene in deionised water. Graphene produced using this approach can be evenly dispersed and suspended in deionised water without the use of a surfactant or stabiliser, and is suitable for storage at room temperature. Ultraviolet–visible spectroscopy was employed to analyse the optical properties of the graphene nanostructure. The Zetasizer system was used to examine the particle size and zeta potential of the graphene nanoparticles, and scanning electron microscopy, energy-dispersive X-ray spectroscopy, and high-resolution transmission electron microscopy were adopted to explore the morphology, size, and dispersion of the particles, using the Raman spectrum, it is observed that there are two characteristic peaks. Without mixing any surfactant or stabiliser in deionised water, the zeta potential of negatively charged graphene nanoparticles was −51.5 mV. The nanoparticles were stably suspended in the deionised water instead of depositing as sediments. The results of this work confirmed that graphene production with submerged arc discharge is a low-cost, fast, and effective manufacturing method.
