| Abstract: | Nanometer CuO was prepared by direct precipitation method with copper chloride and sodium carbonate decahydrate as raw materials.The effects of ultrasonication time,concentration and the ratio of reactants on the dispersion properties of nanoparticles CuO in water were analyzed and the best reaction conditions for preparing nanophase CuO were obtained.The surface modification of nanometer CuO were obtained with two kinds of typical surfactants.The influence of different surfactant on the suspending stability of dispersive system of nanometer CuO was investigated through sedimentation experiment and suitable surfactant were studied. |
