Abstract

In the present study, reduced graphene oxide (rGO) has been synthesized by the Hummers method. The synthesized product was studied by X-ray diffraction, high-resolution scanning electron microscopy (HR-SEM), Fourier transform infrared spectroscopy and Raman spectroscopy. Nanosuspensions with different concentrations have been prepared by dispersing rGO in ethylene glycol (EG) under continuous ultrasonication. Synthesized nanosuspensions were characterized by UV–Vis spectroscopy and dynamic light scattering (DLS) to confirm the distribution, stability, and size of the rGO particles in EG. Rheological studies have been performed on the nanosuspension at room temperature. This study helps to identify the minimum shear level required to make the nanosuspension flow freely.

油墨用还原氧化石墨烯-乙二醇纳米悬浮液的流变学研究

摘要

在本研究中，还原氧化石墨烯 (rGO) 已通过 Hummers 方法合成。通过X射线衍射、高分辨率扫描电子显微镜(HR-SEM)、傅里叶变换红外光谱和拉曼光谱对合成产物进行了研究。通过在连续超声处理下将 rGO 分散在乙二醇 (EG) 中，制备了不同浓度的纳米悬浮液。合成的纳米悬浮液通过紫外-可见光谱和动态光散射 (DLS) 进行表征，以确认 EG 中 rGO 颗粒的分布、稳定性和尺寸。已经在室温下对纳米悬浮液进行了流变学研究。这项研究有助于确定使纳米悬浮液自由流动所需的最小剪切水平。
