▎ 摘　　要

This work proposed a novel approach, in which an impulse underwater discharge was used to produce graphene-graphene oxide material in distilled water. The characteristics of this discharge were presented, including electrical parameters, plasma composition, and electron concentration. Graphene-based material produced using this approach can be evenly dispersed in water without the use of a surfactant or stabilizer, and is suitable for storage at room temperature. Ultraviolet-visible spectroscopy was employed to analyze the optical properties of the graphene-based structures. Scanning electron microscopy was adopted to explore the morphology and size of the particles. The FTIR spectroscopy confirms the formation of graphene oxide. The Raman spectroscopy demonstrates the formation of a graphene-containing multilayer material. The results of this study confirmed that graphene-based material production by impulse underwater discharge is a low-cost, fast, and effective manufacturing method.
