Abstract

This work reports a novel, facile and hydrothermal approach to prepare graphene oxide/NiO/Starch composite materials (GO/NiO/Starch). The composite materials were fully characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray analysis (EDS), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Raman spectroscopy and X-ray photo-electron spectroscopy (XPS), and Thermo gravimetric analysis (TGA-DTA). Furthermore, the antibacterial properties of NiO and starch decorated graphene oxide were tested against Staphylococcus aureus by using the well diffusion method. The obtained results show that the GO/NiO/Starch composite material has a substantial antibacterial activity against Staphylococcus aureus.

摘要

这项工作报告了一种新颖、简便的水热方法来制备氧化石墨烯/NiO/淀粉复合材料（GO/NiO/Starch）。通过扫描电子显微镜 (SEM)、能量色散 X 射线分析 (EDS)、X 射线衍射 (XRD)、傅里叶变换红外光谱 (FTIR)、拉曼光谱和 X 射线光电子能谱对复合材料进行了全面表征(XPS) 和热重分析 (TGA-DTA)。此外，采用井扩散法测试了 NiO 和淀粉修饰的氧化石墨烯对金黄色葡萄球菌的抗菌性能。所得结果表明，GO/NiO/Starch复合材料对金黄色葡萄球菌具有显着的抗菌活性。
