Capillary Wave Analysis and Domain Fusion Process at Immiscible Polymer/Polymer Interfaces

了解聚合物与另一种聚合物接触并相互扩散的聚合物/聚合物界面的形成过程非常重要。在这项研究中，我通过时间分辨中子反射率测量和聚合物相互扩散的数学模型相结合，研究了聚合物界面的实时测量和分析方法。对于不混相聚合物界面的研究，我还利用具有光可切割连接点的二嵌段共聚物制备了模型界面。采用时间分辨小角x射线散射测量方法研究了非混相界面的结构随时间的变化。

It is important to understand the formation process of polymer/polymer interface atwhich a polymer contacts with another and they mutually diffuse. In this study, I studied the methodology of real-time measurements and analyses of polymer interfaces by combination of time-resolved neutron reflectivity measurements andmathematical models for interdiffusion of polymers. For the investigation of immiscible polymer interfaces, I also prepared a model interface by using a diblock copolymer with photo-cleavable junction point. The structural changes in immiscible interfaces with time were examined by time-resolved small angle X-ray scatteringmeasurements.
