在水(溶液)/白油/Span-80+Tween-80/正己醇反相微乳液体系中,用水合肼还原硫酸镍原位一步法制备纳米镍白油稳定分散体.并采用XRD、TEM、分散稳定性等方法对产物进行了表征.结果显示,改变反应条件可制备含不同形貌纳米镍颗粒的白油分散体,其中含球形纳米镍的白油分散体分散稳定性最好,其中镍颗粒的粒径为13 nm.
In the micro-emulsion system consisting of aqueous solution, white oil, Span-80+Tween-80 and n-hexyl alcohol, the stable dispersion of nano-nickel in white oil was prepared by one-step process through reducing NiSO_4 with N2H4·H_2O. The product was characterized by XRD, TEM and disperse stability method. The results showed that the dispersions of nano-nickel with different shapes in white oil could be prepared by changing reactive condition.Among these dispersions, the disperse stability of the spherical nano-nickel dispersion in white oil was the best, whose diameter is about 13 nm.
