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.

分离流体静态和动力学纳米约束作用的纳米流体方法

在这里，我们报告了一种纳米流体方法，该方法首次使人们可以区分二维纳米约束中聚合物结晶的静态和动力学影响。设计用于通过介电常数测量实时监测的纳米流体单元，利用聚合物流入圆柱状纳米孔的过程，研究了在静态和动态限制条件下聚偏二氟乙烯-共-三氟乙烯（PVDF-TrFE）的结晶。据报道，静态约束效应和约束中的流动效应之间存在显着分离。推导了特征时间，以量化流动对2D几何纳米约束条件下发生的聚合物结晶过程的影响。
