在以表面活性剂为模板的仿生合成中,模板的自组装特性是关键环节。由于混合胶团的存在,两种表面活性剂的水溶液体系的效能高于单一表面活性剂溶液;利用试验优选合适的混合表面活性剂用于仿生合成,耗费时间长,成本高。本文从热力角度出发,分析了混合成胶自由能的影响,建立了离子 非离子混合表面活性剂的自组装模型,利用该模型模拟考察了混合表面活性剂的混合临界胶团浓度和胶团组成等参数,得到了其影响因素及作用规律,并进行了部分试验验证,二者吻合得较好。
In biomimetic synthesis with surfactant as a template, the self-assembly of the template is a key issue. Due to the presence of mixed micelles, aqueous solutions of both surfactants are more effective than single surfactant solutions; the use of suitable mixed surfactants for testing, preferably for biomimetic synthesis, is time consuming and costly. In this paper, from the thermal point of view, the influence of the free energy of the mixed plasticizer was analyzed and a self-assembly model of the ionic nonionic mixed surfactant was established. By using this model, the mixed surfactant micelle concentration and micellar composition And other parameters, obtained its influencing factors and the law of action, and carried out some tests to verify that the two agree well with each other.
