共聚物薄膜

共聚物的SAXS图谱,如图二嵌段共聚物薄膜(左)和“展开”方位角与逆埃的比(右)和I/Q(下)。薄膜都是彼此面向90°从而提供四重对称性。散射图像为在麻省大学的高分子科学与工程系通过具有三个长度为3米针孔理学S-MAX3000标准二维SAXS仪器拍摄。X射线源为高亮度MicroMax-002。样品距离探测器距离为1.5米。

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...
