Developing microstructures, such as low molecular aggregates, spherical micelles and multi-compartment micelles, is an expanding area of research in Materials Science. By applying an atom transfer radical polymerization (ATRP) process to cross-linkable fluorinated diblock copolymers and analyzing the data we are able to demonstrate the potential for developing films with different micro-structures for additional biological research. Applying the Dissipative Particle Dynamic (DPD) Method, Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) techniques to cross-linkable fluorinated diblock copolymers of (methyl methacrylate-co-hydroxyethyl methacrylate-co-butyl methacrylate)-b-2-(perfluoroalkyl)ethyl methacrylate (MMA-co-HEMA-co-BMA-b-FMA) we were able to analyze the structures and their relationships to the aggregation of various microstructure formations through the use of various solvents in the process. For the self-assembly of the cross-linkable diblock copolymer in solutions, the DPD simulation results are only in qualitative agreement with experimental data of aggregate morphologies and sizes. This suggests an improved approach to creating materials and methods necessary for studying microstructures in films used in other research areas. Our work examines whether using selective solvents can be easily extended to prepare aggregates with different morphologies, which is an effective shortcut to obtain films with different microstructures. DPD simulation can be considered as an adjunct to experiments and provides other valuable information for the experiment.
开发微观结构,如低分子聚集体、球形胶束和多腔胶束,是材料科学中一个不断发展的研究领域。通过对可交联氟化嵌段共聚物应用原子转移自由基聚合(ATRP)工艺,并对数据进行分析,我们能够展示出开发具有不同微观结构的薄膜的潜力,以进行更多的生物学研究。通过应用耗散粒子动力学(DPD)方法、透射电子显微镜(TEM)和扫描电子显微镜(SEM)技术对可交联氟化嵌段共聚物(甲基丙烯酸甲酯-共-羟乙基甲基丙烯酸酯-共-丁基甲基丙烯酸酯)-b-2-(全氟烷基)乙基甲基丙烯酸酯(MMA-co-HEMA-co-BMA-b-FMA)进行分析,我们能够分析结构及其与各种微观结构形成的聚集之间的关系,通过在该过程中使用各种溶剂。对于可交联嵌段共聚物在溶液中的自组装,DPD 模拟结果仅与聚集形态和尺寸的实验数据定性一致。这表明需要改进方法来创建用于研究其他研究领域中薄膜微观结构的材料和方法。我们的工作研究了是否可以使用选择性溶剂来轻松扩展到制备具有不同形态的聚集体,这是获得具有不同微观结构的薄膜的有效捷径。DPD 模拟可以被视为实验的辅助手段,并为实验提供其他有价值的信息。
