However, in this paper MesoDyn simulation is used to study interactions between polysaccharide and surfactant. A new and simple approach for studying such a system is found. This study enlarges the application of MesoDyn method in colloid chemistry and provides a new idea for investigating interactions between other type of polymer and surfactant.2. The second novelty of this dissertation is mesoscopic simulation and experiments are combined to study physicochemical properties of system.
文献报道的MesoDyn模拟主要用来研究嵌段共聚物或两种聚合物混合体系的性质,而本文首次利用MesoDyn模拟方法研究了聚合物和表面活性剂之间的相互作用,建立了研究这一体系的简易而有效的新途径,从而大大增强了MesoDyn方法在胶体化学中应用的可行性;同时,有助于人们进一步了解MesoDyn方法,并为用其研究其它类型的聚合物与表面活性剂之间的相互作用提供了良好的思路。2。
