We report on the design and operation of a novel sample stage, used to simultaneously measure X-ray scattering profiles and conductivity of a polymer electrolyte membrane (PEM) surrounded by humid air as a function of temperature and relative humidity. We present data obtained at the Advanced Light Source and Stanford Synchrotron Radiation Laboratory. We demonstrate precise humidity control and accurate determination of morphology and conductivity over a wide range of temperatures. The sample stage is used to study structure-property relationships of a semi-crystalline block copolymer PEM, sulfonated polystyrene-block-polyethylene.
我们报告了一种新型样品台的设计与操作，该样品台用于同时测量处于潮湿空气中的聚合物电解质膜（PEM）的X射线散射轮廓和电导率，测量结果是温度和相对湿度的函数。我们展示了在先进光源和斯坦福同步辐射实验室获得的数据。我们证明了在很宽的温度范围内能够实现精确的湿度控制以及对形态和电导率的准确测定。该样品台用于研究半结晶嵌段共聚物PEM（磺化聚苯乙烯-嵌段-聚乙烯）的结构-性能关系。
