| Abstract: | The organic-inorganic nanocomposites are prepared by sol-gel method.The structure of the organic-inorganic nanocomposites is characterized by XRD and FT-IR,the morphology of the organic-inorganic nanocomposites are investigated by means of transmission electron microscopy (TEM).The dynamic interfacial tension between Daqing crude oil and the compounded system of AOS and the organic-inorganic nanocomposite is measured by full-rang interface tension instrument.The results show that the particle size of the prepared organic-inorganic nanocomposites is less than 40 nm;the compounded system of AOS and the organic-inorganic nanocomposite can reduce oil-water interfacial tension (IFT) to the magnitude order of 10-4 mN/m. |
