Characterization Analysis of Graphene Nanoplatelets in Nanoparticles Form

In this paper, graphene nanoplatelets (GNPs) are thoroughly characterized and examined in the form of particles before formulating as nanofluids for heat transfer applications as this study aims to create stable, evenly dispersed GNPs in a base fluid and analyze their thermal and structural properties. This study intends to investigate the morphology of the graphene nanoplatelets before formulating it into a nanofluid. The particle size, morphology, and crystallinity of the GNPs are analyzed using a particle size analyzer, field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD). This study advances the knowledge of GNPs as nanofluids and their use in engineering systems, resulting in more effective and environmentally friendly heat management solutions. Findings from FESEM show the morphology of the GNPs with the size ranging from 98 to 400 µm. The particle size analyzer shows that the GNPs powder size ranges from 100 to 1000 µm, and XRD shows the crystallinity of the graphene has the highest peak.

本文针对石墨烯纳米片（graphene nanoplatelets, GNPs），在将其配制为用于传热应用的纳米流体（nanofluids）之前，以颗粒形式对其开展了全面的表征与检测。本研究旨在制备可在基础流体中稳定均匀分散的GNPs，并分析其热学与结构性能。本研究拟在将GNPs制备为纳米流体之前，对其形貌展开探究。本研究通过粒度分析仪、场发射扫描电子显微镜（field emission scanning electron microscopy, FESEM）以及X射线衍射（X-ray diffraction, XRD），对GNPs的粒径、形貌与结晶度进行了表征分析。本研究深化了GNPs基纳米流体及其在工程系统中应用的相关认知，可为开发更高效且环保的热管理解决方案提供支撑。场发射扫描电子显微镜观测结果显示，GNPs的形貌尺寸介于98至400 µm之间。粒度分析仪检测结果表明，GNPs粉体的粒径分布范围为100至1000 µm，而X射线衍射分析则证实石墨烯的结晶度呈现最高特征峰。
