It is the aim of the project to work out a fundamental understanding of crystallization induced at the interface between a solid substrate and a liquid polymer. Using in-situ AFM we experimentally established prefreezing as one mode of interface induced crystallization and showed that it corresponds to a first order wetting process. In the next funding period, we will extend our studies additionally to heterogeneous nucleation, the other possible process by which an interface can induce crystallization. The work is relevant to understand the function of nucleating agents and the effect of fillers on crystallization in polymers as well as for thin films of functional materials.

该项目的目的是对固体基质和液体聚合物之间界面处诱导的结晶有一个基本的了解。使用原位原子力显微镜，我们通过实验将预冻确立为界面诱导结晶的一种模式，并表明它对应于一级润湿过程。在下一个资助期内，我们将把我们的研究扩展到异质成核，这是界面诱导结晶的另一种可能过程。这项工作与了解成核剂的功能以及填料对聚合物以及功能材料薄膜结晶的影响有关。
