摘　　要： 以全氟辛基磺酸钾为阴离子表面活性剂,以N,N′-二甲基乙酰胺为极性溶剂,利用阴离子插层/超声辅助液相剥离法制备出少层的水滑石纳米片(LDHNSs)。采用SEM、XRD、TEM、AFM和激光粒度仪等测试手段对产物进行表征。结果表明,LDHNSs的厚度为7~17nm,仅为1~4层。 Less layes of hydrotalcite nanosheets(LDHNSs)were prepared by anion exchange/sonication assisted liquid exfoliation with N,N′-dimethylacetamide as organic solvent,using potassium perfluorooctane sulfonate as an anionic surfactant.The product were characterized by means of different technologies,such as Scanning electron microscope(SEM),X-Ray powder diffraction(XRD),Transmission electron microscope(TEM),Atomic Force Microscope(AFM)and Laser particle sizer.The results showed that the thickness of LDHNSs was 7-17 nm and about 1-4 layers.
