To date the scrolled morphology of γ-phase poly(vinylidene fluoride) (PVDF) has been witnessed via high temperature melt crystallization of crystalline thin films and through imaging of chemical etched PVDF bulk films. Here we show the first growth and characterization of free-standing γ-phase PVDF scrolls via solution crystallization. Scanning electron microscopy, transmission electron microscopy, and atomic force microscopy have been used to characterize and to further understand the fundamental preferred crystalline habit of the γ-phase of PVDF.

聚偏氟乙烯纳米卷的结构和形态

迄今为止，通过结晶薄膜的高温熔融结晶和化学蚀刻的 PVDF 体膜的成像，已经见证了 γ 相聚（偏二氟乙烯）（PVDF）的滚动形态。在这里，我们展示了通过溶液结晶的独立 γ 相 PVDF 涡卷的首次生长和表征。扫描电子显微镜、透射电子显微镜和原子力显微镜已被用于表征和进一步了解 PVDF γ 相的基本优选结晶习性。
