EFC的离子交换膜

使用NANOViewer和MettlerHotStage研究聚合物电解质燃料电池(PEFC)的离子交换膜的结构。

结果:

structure of an ion exchange membrane for a polymer electrolyte fuel cell (PEFC)
SAXS图谱(左)和WAXS图谱(右)



1st and 2nd peaks

第一个峰和第二个峰分别来源于分支链和表面活性剂(主要是水),该微观结果的研究结果表明80°C的结果最为理想。

1st, 2nd, and 3rd peaks

第一和第二,第三峰来源于周期结构。“wet”峰扩大表明了结构的置乱。这一宏观结构的结果表明周期结构显示了潮湿环境中结构的置乱。


The S-MAX3000 pinhole SAXS camera design is available with a choice of conventional or high brilliance X-ray sources. A 3-meter, fully evacuated camera length provides both high intensity and high resolution. Coupled with a fully integrated 2-dimensional multi-wire proportional counter, the system is capable of making highly sensitive measurements from both isotropic and anisotropic materials. A wide range of sample stage attachments provide maximum flexibility in controlling environmental sample conditions during measurement. Read more...
