在这里，我们报告了一个nanofluidics的方法，允许一个区分，第一次，静态和动态的影响之间的结晶聚合物在2维nanofinition。纳米流体单元设计成真实的时间监测，通过介电常数测量，到圆柱形纳米孔的聚合物的流动过程中，采用静态和动态约束条件下的聚（偏氟乙烯-共-三氟乙烯）（PVDF-TrFE）的结晶研究。一个显着的分离之间的静态约束效应和流动约束的影响。推导出一个特征时间，以量化流动对聚合物的结晶过程中发生的条件下的2D几何纳米限制的影响。
Here we report a nanofluidics approach that allows one to discriminate, for the first time, between static and kinetic effects on the crystallization of polymers in 2-dimensional nanoconfinement. Nanofluidics cells designed to monitor in real time, via permittivity measurements, the flow process of polymers into cylindrical nanopores were employed to investigate the crystallization of poly(vinylidenefluoride-co-trifluoroethylene) (PVDF-TrFE) under static and under kinetic confinement conditions. A significant separation between static confinement effects and flow effects in confinement is reported. A characteristic time is deduced, to quantify the impact of flow on the crystallization process of polymers taking place under conditions of 2D geometrical nanoconfinement.
