A facile one-step microwave-assisted method was proposed for kaolinite intercalation and grafting. The structure, morphology, composition, and size distribution of kaolinite sheets were investigated using various methods, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric (TG) analysis. The potential application of the modified kaolinite as an oil/water emulsion stabilizer was studied. The results verified that intact kaolinite sheets were obtained. The dodecane/water emulsion stabilized by the modified kaolinite remained stable for more than 60 days. The effective performance suggests that the effectiveness of the proposed kaolinite modification method may be useful for Pickering emulsion stabilization in oil recovery applications.
提出了一种简便的一步微波辅助法来进行高岭石的插层和接枝。采用多种方法研究了高岭石薄片的结构、形貌、组成和粒径分布，包括 X 射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外（FTIR）光谱和热重（TG）分析。研究了改性高岭石作为油水乳液稳定剂的潜在应用。结果证实得到了完整的高岭石薄片。由改性高岭石稳定的十二烷/水乳液稳定 60 天以上。有效的性能表明，所提出的高岭石改性方法的有效性可能对采油应用中的 Pickering 乳液稳定有用。
