水包油微乳法合成氧化铝纳米粒子

Synthesis of Alumina Nanoscale Particles by Oil-in-water Microemulsion

为了探索绿色、无污染的微乳法合成途径,采用水包油微乳法制备了氧化铝纳米粒子。Tween-80和醇作为表面活性剂和助表面活性剂,用超纯水来代替反相微乳液中大量的有机相,既经济又环保。研究了反应温度和反应物的浓度对反应产物的影响。实验结果表明:用水包油微乳液制备的氧化铝纳米粒子粒径小、分散性好。

To explore the green, pollution - free microemulsion synthesis approach, the oil - in - water microemulsion is adopted in the preparation of alumina nanoparticles. Oil is replaced by ultra pure water, which is both economic and environmentally friendly. Tween - 80 and alcohol are used as surfactant and cosurfaetant,respectively. The effects of reaction temperature and reactant concentration on the particle size are studied. The experimental results show that： the alumina nanoparticles prepared by O/W microe- mulsion method have small particle size and good dispersibility.
