Abstract

Graphene nanoplatelets (GNPs) were prepared using the electrolytic exfoliation method on graphite foil in an ammonium sulfate solution. A series of experiments were conducted in order to optimize the production of the flakes by varying the pH of the solution, applied voltage and current, duration of electrolysis, temperature in the electrolytic system, and type and duration of the ultrasound interaction. The quality of the produced graphene nanoplatelets was analyzed using X-ray diffraction, Raman and IR spectroscopy, and TEM.

摘要

采用电解剥离法在硫酸铵溶液中的石墨箔上制备了石墨烯纳米片。进行了一系列实验，通过改变溶液的pH值、施加的电压和电流、电解持续时间、电解系统中的温度以及超声相互作用的类型和持续时间来优化薄片的产量。使用X射线衍射、拉曼光谱和红外光谱以及透射电子显微镜对所制备的石墨烯纳米片的质量进行了分析。
