| 摘 要： | 在明胶阿拉伯胶复合凝聚过程中,通过控制十二烷基硫酸钠(SDS)浓度和搅拌速度,制备了准均匀分散的电子墨水微胶囊。实验表明:随着SDS浓度和搅拌速度的增加,囊芯液滴的平均粒径减小;同时,囊芯液滴的平均粒径的对数与搅拌速度的对数呈现出良好的线性关系。在最佳实验条件(SDS 0.01%(质量分数),搅拌速度800r/min)下获得的微胶囊大小均匀且形状规则、表面光滑无粘连,平均粒径约为40μm,湿胶囊壁厚约为2μm。

| Abstract: | Electronic ink microcapsules in narrow dispersity were prepared by complex coacervation using gelatin and gum Arabic as wall materials. The effect of various parameters, such as sodium dodecyl sulphate (SDS) and agitation rate, was investigated. From experiment, the average diameter and dispersity of core droplets decrease as the concentration of SDS and agitation rate increase. And the relationship between average diameter and agitation rate is linear in log-log scale. The optimal reaction conditions of the synthesis of microcapsules were (0.01)wt% of SDS and 800r/min of agitation. The capsules prepared by the optimized process are even and regular and their surfaces are smooth. The diameter of the capsules and the thickness of the shell wall were about 40 and 2 microns, respectively. |
