聚苯乙烯三嵌段共聚物SEBS

聚苯乙烯聚(乙烯-r-丁烯)-聚苯乙烯三嵌段共聚物 (SEBS)的SAXS图谱,面向平面应变压缩 (左)和“展开”方位角与逆埃的比(右)。散射图像通过Richard A教授小组使用理学聚焦S-MAX3000 SAXS系统与一个MicroMax-002+微焦点X射线源拍摄。注册在普林斯顿,新泽西普林斯顿大学化工系。

SEBS self-assembless

SAXS图谱显示了SEBS自我装配成有序的柱形结构和参数,如下图所示。SAXS数据显示了气瓶中极强的流动方向(FD)。点焦点SAXS仪器可以用于表示样品中任何点的定向。

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...
