Preparation of microcapsules with aqueous core and polyamide walls is influenced by several factors. We improved the stability of walls and size of capsules by simultaneous variation of four factors: total ratio of polymer, ratio of amines to acid chlorides, concentration of surfactant and speed of stirring. Use of factorial design minimizes the number of experiments and permits us to know the influence of these factors and of their interactions. By increasing the ratio of amines to acid chlorides and with a low concentration of total polymer, we obtained more stable capsules. Surfactant had a negative effect on the hardness of the polymer.
制备具有水相核心和聚酰胺壁的微胶囊受到多种因素的影响。我们通过同时改变四个因素来提高壁的稳定性和胶囊的尺寸：聚合物的总比例、胺与酰氯的比例、表面活性剂的浓度和搅拌速度。使用析因设计可减少实验次数，并使我们了解这些因素及其相互作用的影响。通过增加胺与酰氯的比例以及降低总聚合物的浓度，我们获得了更稳定的胶囊。表面活性剂对聚合物的硬度有负面影响。
