摘　　要：在对直流氢电弧蒸发法制备的金属纳米镍粉、铜粉及铜镍复合粉体的Zeta电位测量的基础上,采用油酸作为表面改性剂,系统研究了超声分散时间和油酸添加量对3种粉体在无水乙醇中分散性能的影响。研究结果表明,所制备金属纳米粉体表面均带有正电荷,油酸对3种粉体均具有较好的分散作用。On the basis of Zeta value measurement of the nanometer nickel, copper and composite copper and nickel powders prepared by the DC Arc Plasma evaporation, the influence of supersonic dispersing time and oleic acid mass friction on the dispersing properties of the three powders in alcohol solvent was studied systematically, in which oleic acid was employed as surfactants. The results show that all of the three powders＇ surface have positive charge and oleic acid has great effects on improving their dispersing properties.
