利用微乳液制备超细硫化镍粒子的研究
Preparation of nickel sulfide nanoparticles by the method of microemulsions
【摘要】 选择溶水量较大的微乳液作为反应介质、适宜浓度的盐溶液作为反应物制备硫化镍粒子,通过透射电镜(TEM)观察所得硫化镍粒子的形状及大小。结果表明,硫化镍超细粒子的大小可以通过调节盐溶液浓度、水/表面活性剂摩尔比及表面活性剂浓度来控制。硫化镍粒子的形状也因微乳液组成不同而变化。
【Abstract】 A suitable microemulsions and salt solutions were choosen to prepare nickel sulfide nanoparticles.By TEM,the dimensions and the forms of the formed nickel sulfide nanoparticles have been investigated.The result shows that the size of nickel sulfide nanoparticles can be controued by changing the concentration of the salt solutions,the ratio of water to surfactant molecules and the concentration of the surfactant.Moreover,the forms of the nanoparticles change due to the different composition of microemulsions.
