摘要/Abstract

摘要： 本文以纳米二氧化钛(TiO2)为芯材，明胶和阿拉伯胶为壁材，研究复凝聚法制备TiO2微胶囊的工艺。以微胶囊的平均粒径、包埋率和粒径分布方差作为评价工艺优劣的指标，利用正交试验法研究反应溶液pH值、反应温度、搅拌速率和壁材质量分数对微胶囊成囊效果的影响。通过优化工艺，获得最佳的工艺参数：溶液pH值为4.2、壁材质量分数为2%、反应温度50℃、搅拌转速为750r?min-1，在上述条件下，所得微胶囊平均粒径为90.1μm，包埋率超过86.2%，粒径分布方差12.1。

Abstract: The preparation of nano-TiO2 microcapsule by complex coacervation was studied in this paper. Nano-TiO2 was selected as the core material and the gelatin and Arabic gum was selected as coating materials. The average particle size, embedding rate, and particle size variance of microcapsules were used to evaluate the technology of preparation. The factors such as pH value, reaction temperature, content of wall materials and stirring speed, were investigated to obtain the most optimal preparation. The results showed that the optimal conditions were as follows: emulsifying 1 % of Arabic gum and 1 % of gelatin, reaction at pH 4.2, solidifying at 50℃, and stirring with a speed of 750 r?min-1. Under the above condition，microcapsules’ average particle size was 90.1μm , embedding rate was about 85% and particle size variance was 12.1.

Key words: nano-TiO2, microcapsule, gelatin, arabic gum
