Abstract Physical and chemical characteristics of few-layer graphene structures (FLGS) obtained in various modes of electrochemical exfoliation of graphite have been studied. The FLGS synthesis was performed by the application of voltage pulses from a high current generator to the graphite electrodes immersed in an electrolyte solution. FLGS were characterized with scanning electron microscopy, infrared, X-ray photoelectron, and electron paramagnetic resonance spectroscopy. The suggested one-step synthesis allows a controlled variation of typical size of FLGS and the content of oxygen functional groups on the FLGS surface in the range from 7 to 26 at. %, with the highest degree of functionalization by oxygen functional groups such as OH/C-O-C and C = O achieved in the case of the anode plasma-assisted electrochemical exfoliation of graphite.

通过电压脉冲在石墨电化学剥离的不同模式下生产少层石墨烯结构

摘要 研究了在石墨电化学剥离的各种模式下获得的少层石墨烯结构 (FLGS) 的物理和化学特性。FLGS 合成是通过将来自高电流发生器的电压脉冲施加到浸入电解质溶液中的石墨电极来进行的。FLGS 的特点是扫描电子显微镜、红外、X 射线光电子和电子顺磁共振光谱。建议的一步合成允许 FLGS 的典型尺寸和 FLGS 表面上氧官能团的含量在 7 到 26 at 的范围内受控变化。%，在阳极等离子体辅助石墨电化学剥离的情况下，氧官能团（如 OH/COC 和 C = O）的官能化程度最高。
