Reduced graphene oxide (rGO) was synthesized by chemically reducing graphene oxide (GO) using a reducing agent. The product, rGO, showed excellent hydrophobicity, as indicated by its high-water contact angle, which was greater than 150°. Characterizations using Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, and X-ray diffraction (XRD) were used to analyze the composition and structural differences between GO and the superhydrophobic rGO material. Scanning electron microscopy (SEM) showed that GO particles exhibited a plate-like morphology with layers of stacked plates, while rGO displayed fewer stacks that show a more separated structure of layers. The increasing demand for superhydrophobic materials in advanced materials industries, due to their potential to enhance performance, durability, and safety, makes rGO a promising candidate for use in composite materials.
通过使用还原剂对氧化石墨烯（GO）进行化学还原，合成了还原氧化石墨烯（rGO）。产物rGO表现出优异的疏水性，其高水接触角大于150°即表明了这一点。使用傅里叶变换红外（FTIR）光谱、拉曼光谱和X射线衍射（XRD）进行表征，以分析GO与超疏水rGO材料之间的组成和结构差异。扫描电子显微镜（SEM）显示，GO颗粒呈现出层状堆叠板的片状形态，而rGO显示出较少的堆叠，呈现出更分离的层结构。由于超疏水材料在先进材料行业中对提高性能、耐久性和安全性具有潜力，对其需求不断增加，这使得rGO成为用于复合材料的有前途的候选材料。
