Graphene, as the earliest discovered two-dimensional (2D) material, possesses excellently physical and chemical properties. Vast synthetic strategies, including chemical vapor deposition, mechanical exfoliation, and chemical reduction, are proposed. In this paper, a method to synthesize multilayer graphene in a semi-opened environment is presented by introducing arc-discharge plasma technology. Compared with previous technologies, the toxic gases and hazardous chemical components are not generated in the whole process. The synthesized carbon materials were characterized by transmission electron microscopy, atomic force microscopy, X-ray diffraction, and Raman spectra technologies. The paper offers an idea to synthesize multilayer graphene in a semi-opened environment, which is a development to produce graphene with arc-discharge plasma.
石墨烯作为最早被发现的二维材料，具有优异的物理和化学性质。人们提出了大量的合成策略，包括化学气相沉积、机械剥离和化学还原。本文通过引入电弧放电等离子体技术，提出了一种在半开放环境中合成多层石墨烯的方法。与以往技术相比，整个过程不产生有毒气体和有害化学成分。采用透射电子显微镜、原子力显微镜、X射线衍射和拉曼光谱技术对合成的碳材料进行了表征。本文提供了一种在半开放环境中合成多层石墨烯的思路，这是利用电弧放电等离子体生产石墨烯的一项进展。
