利用耗散粒子动力学模拟研究了在水溶液中混合不同的线形三嵌段共聚物AxByCz和线形两嵌段共聚物AmBn对多室胶束的形貌多样性的影响.通过改变线形的三嵌段共聚物和两嵌段共聚物的链长来寻找多室胶束的形成条件.由线形三嵌段共聚物和线形两嵌段共聚物的不同混合形成的多室胶束结构是多种多样的,例如“蠕虫状”胶束、“汉堡包”胶束、“球上球”胶束、“核-壳-壳”胶束等等.多室胶束的整体形貌和内部结构的控制都可以从线形三嵌段共聚物和两嵌段共聚物的二元共混得到.为了表征获得的多室胶束结构,我们计算了密度图和成对分布函数图.在此工作中,可以获得和观察到复杂的多室胶束.结果表明,简单地混合线形的三嵌段共聚物和线形的两嵌段共聚物是一个控制多室胶束形貌和结构的有效方法,在工程实验中可以更简单更经济地形成多室胶束结构.因此,在设计新的多室胶束方面,聚合物共混仍然是未来值得更加关注的一个话题.
The effect of mixing different linear triblock copolymer AxByCz and linear diblock copolymer AmBn on morphology diversity of multi-compartment micelles was studied by dissipative particle dynamics simulation. By changing the linear triblock Copolymer and diblock copolymer chain length to find the conditions for the formation of multi-chamber micelles by the linear triblock copolymer and linear diblock copolymer formed by the different mixture of multi-chamber micelles structure is varied Such as “worm-like” micelles, “hamburger” micelles, “ball on the ball” micelles, “core- shell- shell” micelles, Both topography and internal structure control can be obtained by binary blending of linear triblock copolymer and diblock copolymer.In order to characterize the multi-compartment micellar structure obtained, we calculated the density and pairwise distribution function plots. In this work, complex multi-chamber micelles can be obtained and observed.The results show that the simple mixed linear triblock copolymer and linear diblock copolymer is a multi-chamber micelles morphology and structure Effective method, in the engineering experiment can be more simple and more economical to form multi-chamber micellar structure.Therefore, Multi-chamber design of the new aspects of the micelles, polymer blends is still more concerned about the future worth of a topic.
